xfs: use blkdev_report_zones_cached()



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.
