[PATCH] blk_iocost: remove some dupicate irq disable/enables

[Dan Carpenter]

These are called from blkcg_print_blkgs() which already disables IRQs so
disabling it again is wrong.  It means that IRQs will be enabled slightly
earlier than intended, however, so far as I can see, this bug is harmless.

Fixes: 35198e323001 ("blk-iocost: read params inside lock in sysfs apis")
