bfa: Brocade BFA FC SCSI driver

Hello Jing Huang,

The patch 7725ccfda597: "[SCSI] bfa: Brocade BFA FC SCSI driver" from Sep 23, 2009, leads to the following static checker warning:

	drivers/scsi/bfa/bfa_fcs_fcpim.c:596 bfa_fcs_itnim_create()
	error: potentially using uninitialized 'itnim'.

drivers/scsi/bfa/bfa_fcs_fcpim.c
588 struct bfa_fcs_lport_s *port = rport->port;

   589          struct bfa_fcs_itnim_s *itnim;
                                        ^^^^^
   590          struct bfad_itnim_s   *itnim_drv;
   591  
   592          /*
   593           * call bfad to allocate the itnim
   594           */
   595          bfa_fcb_itnim_alloc(port->fcs->bfad, &itnim, &itnim_drv);
                                                      ^^^^^

This function should probably return negative error codes on failure.

   596          if (itnim == NULL) {
                    ^^^^^^^^^^^^^
   597                  bfa_trc(port->fcs, rport->pwwn);
   598                  return NULL;
   599          }
