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

[Chaitanya Kulkarni <kch@nvidia.com>]

The queue variable is only used to check if it is NULL or not in
__blkdev_issue_zero_pages(). The return value of the bdev_get_queue()
will not be NULL based on the comment in the bdev_get_queue().

Remove the variable and respective NULL check.
