Subject: [PATCH -next] scsi: fnic: Remove set but not used variable 'vdev'

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

drivers/scsi/fnic/vnic_wq.c: In function 'vnic_wq_alloc_bufs':
drivers/scsi/fnic/vnic_wq.c:50:19: warning:
 variable 'vdev' set but not used [-Wunused-but-set-variable]

drivers/scsi/fnic/vnic_rq.c: In function 'vnic_rq_alloc_bufs':
drivers/scsi/fnic/vnic_rq.c:30:19: warning:
 variable 'vdev' set but not used [-Wunused-but-set-variable]

It never used since introduction
