xfs: don't allow overly small or large realtime volumes
commit e1429380 upstream. [backport: resolve merge conflicts due to refactoring rtbitmap/summary macros and accessors] Don't allow realtime volumes that are less than one rt extent long. This has been broken across 4 LTS kernels with nobody noticing, so let's just disable it. Signed-off-by:Darrick J. Wong <djwong@kernel.org> Reviewed-by:
