caif: fix a signedness bug in cfpkt_iterate()
The cfpkt_iterate() function can return -EPROTO on error, but the
function is a u16 so the negative value gets truncated to a positive
unsigned short. This causes a static checker warning.
The only caller which might care is cffrml_receive(), when it's checking
the frame checksum. I modified cffrml_receive() so that it never says
-EPROTO is a valid checksum.
Also this isn't ever going to be inlined so I removed the "inline".
