Source kernel commit: 7ee7c9b39ed36caf983706f5b893cc5c37a79071
Non-rtg file systems have a fake RT group even if they do not have a RT
device, and thus an rgcount of 1. Ensure xfs_update_last_rtgroup_size
doesn't fail when called for !XFS_RT to handle this case.
Fixes: 87fe4c34a383 ("xfs: create incore realtime group structures")
