caif: Do not dereference NULL in chnl_recv_cb()
In net/caif/chnl_net.c::chnl_recv_cb() we call skb_header_pointer()
which may return NULL, but we do not check for a NULL pointer before
dereferencing it.
This patch adds such a NULL check and properly free's allocated memory
and return an error (-EINVAL) on failure - much better than crashing..
