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

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

coccinelle report:
./drivers/scsi/mvsas/mv_init.c:699:8-16:
WARNING: use scnprintf or sprintf
./drivers/scsi/mvsas/mv_init.c:747:8-16:
WARNING: use scnprintf or sprintf

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
