btrfs: use blkdev_report_zones_cached()
Modify btrfs_get_dev_zones() and btrfs_sb_log_location_bdev() to replace
the call to blkdev_report_zones() with blkdev_report_zones_cached() to
speed-up mount operations. btrfs_get_dev_zone_info() is also modified to
take into account the BLK_ZONE_COND_ACTIVE condition, which is
equivalent to either BLK_ZONE_COND_IMP_OPEN, BLK_ZONE_COND_EXP_OPEN or
BLK_ZONE_COND_CLOSED.
With this change, mounting a freshly formatted large capacity (30 TB)
SMR HDD completes under 100ms compared to over 1.8s before.
