The parameter max_hw_wzeroes_unmap_sectors in queue_limits should be
equal to max_write_zeroes_sectors if it is set to a non-zero value.
However, when the backend bdev is specified, this parameter is
initialized to UINT_MAX during the call to blk_set_stacking_limits(),
while only max_write_zeroes_sectors is adjusted. Therefore, this
discrepancy triggers a value check failure in blk_validate_limits().
Since the drvd driver doesn't yet support unmap write zeroes, so fix
this failure by explicitly setting max_hw_wzeroes_unmap_sectors to
zero.
