dm thin: support a non power of 2 discard_granularity

Support a non-power-of-2 discard granularity in dm-thin, now that the block
layer supports this(via 7ee99be492139c8218646740d2b7a0910b000253 "block:
discard granularity might not be power of 2" and
948deb46283e376e4bd413859723ce24fe0ceb0a "blk: avoid divide-by-zero with zero
discard granularity").
