block, blk-sysfs: Use the variable directly instead of a function call

In the function blk_register_queue(), var _dev_ is already assigned by disk_to_dev().So use it directly instead of calling disk_to_dev() again. Signed-off-by: Liu Yuan <[email protected]> Modified by me to delete an empty line in the same function while in there anyway. Signed-off-by: Jens Axboe <[email protected]>
