gfs2: Recursive gfs2_quota_hold in gfs2_iomap_end
commit 7009fa9c upstream. When starting an iomap write, gfs2_quota_lock_check -> gfs2_quota_lock -> gfs2_quota_hold is called from gfs2_iomap_begin. At the end of the write, before unlocking the quotas, punch_hole -> gfs2_quota_hold can be called again in gfs2_iomap_end, which is incorrect and leads to a failed assertion. Instead, move the call to gfs2_quota_unlock before the call to punch_hole to fix that.
