[PATCH] blk-sysfs: Make structure queue_attr_group constant

[Nishka Dasgupta <nishkadg.linux@gmail.com>]

The static structure queue_attr_group is used only once, when it is
passed as the second argument to the function sysfs_create_group().
However, the second parameter of sysfs_create_group() is already defined
as constant. Hence make queue_attr_group itself constant, as it is never
modified.
Issue found with Coccinelle.
