iwlwifi: handle RFKILL logic in the transport layer
No HCMD can be sent while RFKILL is asserted. If a SYNC
command is running while RFKILL is asserted the fw will
silently discard it. This means that the driver needs to
wake the process that sleeps on the CMD_SYNC.
Since the RFKILL interrupt is handled in the transport layer
and the code that sleeps in CMD_SYNC is also in the transport
layer, all this logic can be handled there.
This simplifies the work of the op_mode.
So the transport layer will now return -ERFKILL when a CMD
is sent and RFKILL is asserted. This will be the case even
when the CMD is SYNC. The transport layer will return
-ERFKILL straight away.
