btrfs: bail out reclaim process if filesystem is read-only
When a filesystem is read-only, we cannot reclaim a block group as it
cannot rewrite the data. Just bail out in that case.
Note that it can drop block groups in this case. As we did
sb_start_write(), read-only filesystem means we got a fatal error and
forced read-only. There is no chance to reclaim them again.
Fixes: 18bb8bbf13c1 ("btrfs: zoned: automatically reclaim zones")
