scsi: libfc: Prevent integer overflow in fc_fcp_recv_data()
The "offset" comes from the skb->data that we received. Here the code
is verifying that "offset + len" is within bounds however it does not
take integer overflows into account. Use size_add() to be safe.
This would only be an issue on 32bit systems which are probably a very
small percent of the users. Still, it's worth fixing just for
correctness sake.
