scsi: lpfc: Remove set but not used variable 'phys_id'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/scsi/lpfc/lpfc_init.c: In function 'lpfc_cpu_affinity_check':
drivers/scsi/lpfc/lpfc_init.c:10599:19: warning:
 variable 'phys_id' set but not used [-Wunused-but-set-variable]

It never used since introduction in commit 6a828b0f ("scsi: lpfc:
Support non-uniform allocation of MSIX vectors to hardware queues")
