usb: phy: Fix deferred probing
Commit 1290a958d48e ("usb: phy: propagate __of_usb_find_phy()'s error on
failure") actually broke the deferred probing mechanism, since it now returns
EPROBE_DEFER only when the try_module_get call fails, but not when the phy
lookup does.
All the other similar functions seem to return ENODEV when try_module_get
fails, and the error code of either __usb_find_phy or __of_usb_find_phy
otherwise.
In order to have a consistent behaviour, and a meaningful EPROBE_DEFER, always
return EPROBE_DEFER when __(of_)usb_find_phy fails to look up the requested
phy, that will be propagated by the caller, and ENODEV if try_module_get fails.
