common: add zoned block device checks

dm-error and dm-snapshot does not have DM_TARGET_ZONED_HM nor
DM_TARGET_MIXED_ZONED_MODEL feature and does not implement
.report_zones(). So, it cannot pass the zone information from the down
layer (zoned device) to the upper layer.

Loop device also cannot pass the zone information.

This patch requires non-zoned block device for the tests using these
ones.
