[GFS2] Fix ordering of page disposal vs. glock_dq
In case of unlinked files with dirty pages GFS2 wasn't clearing
the pages in quite the right order. This patch clears the pages
earlier (before the qlock_dq) to avoid the situation that the
release of the glock results in attempting to write back data that
has already been deallocated.
This fixes Red Hat bugzilla: #220117
