Subject: [PATCH 1/3] xfs: remove dax EXPERIMENTAL warning

As there seems to be no significant outstanding concern about
dax on xfs at this point, remove the scary EXPERIMENTAL
warning when in use.

(dax+reflink is still unimplemented, but that can be considered
a future feature, and doesn't require a warning for the
non-reflink usecase.)
