Dan Carpenter 120642726e 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.
