From: Bob Peterson <rpeterso@redhat.com>

This is patch 5 of 5 for bug #248176

Metadata corruption was occurring because page references weren't
being removed in all cases. I previously added a function called
detach_bufdata, but I discovered there already WAS a function out
there to do the job. It's called gfs2_meta_cache_flush. So I added
a call to that to remove the page references.
