[SCSI] megaraid_sas: remove sysfs dbg_lvl world writeable permissions

Browse source 
/sys/bus/pci/drivers/megaraid_sas/dbg_lvl defaults to being
world-writable, which seems bad (letting any user affect kernel driver
behavior and logging level).

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