gfs2: remove unneeded pg_oflow variable
Function gfs2_write_disk_quota checks if its write overflows onto another page, and if so, does a second write. Before this patch it kept two variables for this, but only one is needed. This patch simplifies it by eliminating pg_oflow. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
