Subject: [PATCH -next] scsi: fnic: Remove unused function fnic_scsi_host_start/end_tag()

The function fnic_scsi_host_start_tag() and fnic_scsi_host_end_tag() are not used anywhere, so remove them.

silence the warnings:
drivers/scsi/fnic/fnic_scsi.c:2175:1: warning: unused function 'fnic_scsi_host_start_tag'
drivers/scsi/fnic/fnic_scsi.c:2196:1: warning: unused function 'fnic_scsi_host_end_tag'
