scsi: bfa: Remove set but unused variable 'rp'

scsi: bfa: Remove set but unused variable 'rp'

This change subsequently makes 'rp_fcs' unused also.  Remove that too.

Fixes the following W=1 kernel build warning(s):

 drivers/scsi/bfa/bfa_fcpim.c: In function ‘bfa_fcpim_lunmask_delete’:
 drivers/scsi/bfa/bfa_fcpim.c:2338:22: warning: variable ‘rp’ set but not used [-Wunused-but-set-variable]
 2338 | struct bfa_rport_s *rp = NULL;
 | ^~
