Fixes gcc '-Wunused-but-set-variable' warnings:
drivers/scsi/lpfc/lpfc_init.c: In function lpfc_setup_cq_lookup:
drivers/scsi/lpfc/lpfc_init.c:9359:30: warning: variable qp set but not used [-Wunused-but-set-variable]
It's not used since commit e70596a60f88 ("scsi: lpfc: Fix
poor use of hardware queues if fewer irq vectors")
