-stable review patch. If anyone has any objections, please let us know.
------------------
Correct handling of fc_remote_port_add() failure case.
Immediately return if fc_remote_port_add() fails to allocate
resources for the rport. Original code would result in NULL
pointer dereference upon failure.
