gfs2: Remove quota allocation info from quota file

Function do_sync called gfs2_qa_get and put for quota allocation data.
But the inode in question is the system master quota file, which is
never subject to quotas. Therefore, a qa structure should be unnecessary
and if anything accesses it, it's probably a bug.
