Christoph Hellwig 0000f2f720 xen-blkback: use bdev_discard_alignment
Use bdev_discard_alignment to calculate the correct discard alignment
offset even for partitions instead of just looking at the queue limit.

Also switch to use bdev_discard_granularity to get rid of the last direct
queue reference in xen_blkbk_discard.
