Subject: [PATCH] xfs: fix xfs_group release bug in xfs_dax_notify_dev_failure

Chris Mason reports that his AI tools noticed that we were using xfs_perag_put and xfs_group_put to release the group reference returned by xfs_group_next_range. However, the iterator function returns an object with an active refcount, which means that we must use the correct function to release the active refcount, which is _rele.
