dm zero: add discard support
Add zero_io_hints() and set discard limits so that the zero target
advertises support for discards.
The zero target will ignore discards.
This is useful when the user combines dm-zero with other
discard-supporting targets in the same table; without dm-zero support,
discards would be disabled for the whole combined device.
