- Fix DM thinp's discard passdown to properly account for extra
reference that is taken to guard against reallocating a block before a
discard has been issued.
- Fix bio-based DM's redundant IO accounting that was occurring for bios
that must be split due to the nature of the DM target (e.g. dm-stripe,
dm-thinp, etc).
