[Jiapeng Chong <jiapeng.chong@xxxxxxxxxxxxxxxxx>]

Fix the following coccicheck warnings:

./drivers/scsi/scsi_transport_iscsi.c:4453:61-62: WARNING opportunity
for kobj_to_dev().

./drivers/scsi/scsi_transport_iscsi.c:4309:61-62: WARNING opportunity
for kobj_to_dev().

./drivers/scsi/scsi_transport_iscsi.c:4040:61-62: WARNING opportunity
for kobj_to_dev().
