scsi: fnic: make some symbols static

Fix the following sparse warning:

drivers/scsi/fnic/vnic_dev.c:257:5: warning: symbol 'vnic_dev_cmd1' was
not declared. Should it be static?
drivers/scsi/fnic/vnic_dev.c:319:5: warning: symbol 'vnic_dev_cmd2' was
not declared. Should it be static?
drivers/scsi/fnic/vnic_dev.c:414:5: warning: symbol
'vnic_dev_init_devcmd1' was not declared. Should it be static?
drivers/scsi/fnic/vnic_dev.c:425:5: warning: symbol
'vnic_dev_init_devcmd2' was not declared. Should it be static?
drivers/scsi/fnic/vnic_dev.c:495:6: warning: symbol
'vnic_dev_deinit_devcmd2' was not declared. Should it be static?
drivers/scsi/fnic/vnic_dev.c:506:5: warning: symbol
'vnic_dev_cmd_no_proxy' was not declared. Should it be static?
