xfs: require a relatively recent V5 filesystem for LARP mode
While reviewing the FIEXCHANGE code in XFS, I realized that the function
that enables logged xattrs doesn't actually check that the superblock
has a LOG_INCOMPAT feature bit field. Add a check to refuse the
operation if we don't have a V5 filesystem...
...but on second though, let's require either reflink or rmap so that we
only have to deal with LARP mode on relatively /modern/ kernel. 4.14 is
about as far back as I feel like going.
Seeing as LARP is a debugging-only option anyway, this isn't likely to
affect any real users.
