dm vdo: add hash locks and hash zones
In order to deduplicate concurrent writes of the same data (to different
locations), data_vios which are writing the same data are grouped together
in a "hash lock," named for and keyed by the hash of the data being
written. Each hash lock is assigned to a hash zone based on a portion of
its hash.
