block: introduce blk_queue_clear_zone_settings()
Introduce the internal function blk_queue_clear_zone_settings() to cleanup all limits and resources related to zoned block devices. This new function is called from blk_queue_set_zoned() when a disk zoned model is set to BLK_ZONED_NONE. This particular case can happens when a partition is created on a host-aware scsi disk.
