caif: Bugfix for socket priority, bindtodev and dbg channel.
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
