scsi: bfa: bfa_svc.c: make two functions static

Fix the following sparse warning:

drivers/scsi/bfa/bfa_svc.c:4288:1: warning: symbol
'bfa_fcport_ddportenable' was not declared. Should it be static?
drivers/scsi/bfa/bfa_svc.c:4297:1: warning: symbol
'bfa_fcport_ddportdisable' was not declared. Should it be static?
