Subject: [PATCH] scsi: be2iscsi: replace snprintf with sysfs_emit

From: Yang Guang <yang.guang5@....com.cn>

coccinelle report:
./drivers/scsi/be2iscsi/be_mgmt.c:1251:9-17:
WARNING: use scnprintf or sprintf

WARNING: use scnprintf or sprintf

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
