[PATCH 1/4] blk-lib: don't check bdev_get_queue() NULL check

[Chaitanya Kulkarni <kch@nvidia.com>]

Based on the comment present in the bdev_get_queue()
bdev->bd_disk->queue can never be NULL. Remove the NULL check for the
local variable q that is set from bdev_get_queue() in the function
__blkdev_issue_discard().
