afr: warn if pending xattrs missing during init()
Since commit 6e635284a4411b816d4d860a28262c9e6dc4bd6a
(glusterfs-3.7.7), the afr pending xattrs are stored in the volfile and used
by afr when it initializes. If a cluster is upgraded, prevent afr from loading
until the op-version has been bumped up to 3.7.7 and the volfiles have been
regenerated using a volume set command.
Without this fix, AFR will crash when initialzing.
