Modify xfs_mount_zones() to replace the call to blkdev_report_zones() with blkdev_report_zones_cached() to speed-up mount operations. Since this causes xfs_zone_validate_seq() to see zones with the BLK_ZONE_COND_ACTIVE condition, this function is also modified to acept this condition as valid. With this change, mounting a freshly formatted large capacity (30 TB) SMR HDD completes under 2s compared to over 4.7s before.
