dm: Introduce dm_report_zones()
To simplify the implementation of the report_zones operation of a zoned
target, introduce the function dm_report_zones() to set a target
mapping start sector in struct dm_report_zones_args and call
blkdev_report_zones(). This new function is exported and the report
zones callback function dm_report_zones_cb() is not.
dm-linear, dm-flakey and dm-crypt are modified to use dm_report_zones().
