dm stripe: support discards
The DM core will submit a discard bio to the stripe target for each
stripe in a striped DM device. The stripe target will determine
stripe-specific portions of the supplied bio to be remapped into
individual (at most 'num_discard_requests' extents). If a given
stripe-specific discard bio doesn't touch a particular stripe the bio
will be dropped.
