[SCSI] libfc: Don't assume response request present.
Fix NULL pointer dereference crash occurs in fc_lport_bsg_request()
for bsg requests that do not contain a response request.
Specifically, FC_BSG_HST_ADD_RPORT and FC_BSG_HST_DEL_RPORT bsg
requests are not guaranteed to include a response request.
