btrfs-progs: mkfs: check metadata redundancy
Currently BTRFS allows you to make bad choices of data and
metadata levels. For example -d raid1 -m raid0 means you can
only use half your total disk space, but will lose everything
if 1 disk fails. It should give a warning in these cases.
When making a filesystem, check that metadata mode is at least
as redundant as the data mode. For example give warning when:
-d raid1 -m raid0
