[PATCH] scsi: megaraid: Use sysfs_emit in show function callsbacks

[Anup Sharma]

As stated in the Documentation/filesystems/sysfs.rst file, it
is recommended that the show() callback function for kobject
attributes strictly utilizes sysfs_emit instead of the sprintf
family of functions.
Issue identified using the coccinelle device_attr_show.cocci script.
