[PATCH] [SCSI] megaraid_sas: remove sysfs dbg_lvl world writeablepermissions

[Casey Dahlin]

From: Bryn M. Reeves <bmr@xxxxxxxxxx>

/sys/bus/pci/drivers/megaraid_sas/poll_mode_io defaults to being
world-writable, which seems bad (letting any user affect kernel driver
behavior).

This turns off group and user write permissions, so that on typical
production systems only root can write to it.
