In the original code we check if (servl == NULL) twice. The first time
should print the message that cfmuxl_remove_uplayer() failed and set
"ret" correctly, but instead it just returns success. The second check
should be checking the value of "ret" instead of "servl".

Changes:
o Bugfix: SO_PRIORITY for SOL_SOCKET could not be handled
in caif's setsockopt, using the struct sock attribute priority instead.
o Bugfix: SO_BINDTODEVICE for SOL_SOCKET could not be handled
in caif's setsockopt, using the struct sock attribute ifindex instead.
o Wrong assert statement for RFM layer segmentation.
o CAIF Debug channels was not working over SPI, caif_payload_info
containing padding info must be initialized.
o Check on pointer before dereferencing when unregister dev in caif_dev.c

This patch standardizes caif message logging prefixes.
Add #define pr_fmt(fmt) KBUILD_MODNAME ":%s(): " fmt, __func__
Add missing "\n"s to some logging messages
Convert pr_warning to pr_warn
This changes the logging message prefix from CAIF: to caif:
for all uses but caif_socket.c and chnl_net.c. Those now use
their filename without extension.

Previously CAIF supported maximum transfer size of ~4050.
The transfer size is now calculated dynamically based on the
link layers mtu size.

"phyinfo" can never be null here because we assigned it an address, so I
removed both the assert and the second check inside the if statement. I
removed the "phyinfo->phy_layer != NULL" check as well because that was
asserted earlier.
Walter Harms suggested I move the "phyinfo->phy_ref_count++;" outside
the if condition for readability, so I have done that.

Use kzalloc rather than the combination of kmalloc and memset.
A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression x,size,flags;
statement S;
@@
-x = kmalloc(size,flags);
+x = kzalloc(size,flags);
if (x == NULL) S
-memset(x, 0, size);
// </smpl>

Changes:
o Function cfcnfg_disconn_adapt_layer is changed to do asynchronous
disconnect, not waiting for any response from the modem. Due to this
the function cfcnfg_linkdestroy_rsp does nothing anymore.
o Because disconnect may take down a connection before a connect response
is received the function cfcnfg_linkup_rsp is checking if the client is
still waiting for the response, if not a disconnect request is sent to
the modem.
o cfctrl is no longer keeping track of pending disconnect requests.
o Added function cfctrl_cancel_req, which is used for deleting a pending
connect request if disconnect is done before connect response is received.
o Removed unused function cfctrl_insert_req2
o Added better handling of connect reject from modem.
