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.
