Add a helper to query the number of sectors support per each discard bio
based on the block device and use this helper to stop various places from
poking into the request_queue to see if discard is supported and if so how
much. This mirrors what is done e.g. for write zeroes as well.
Just use bdev_alignment_offset in disk_discard_alignment_show instead.
That helpers is the same except for an always false branch that doesn't
matter in this slow path.

Hi Jens,
this series cleanups up the block layer API so that APIs consumed
by file systems are (almost) only struct block_devic based, so that

and
