Subject: [PATCH 2/2] KMS: fix EDID detailed timing frame rate

When KMS has parsed an EDID "detailed timing", it leaves the frame
rate zeroed. Consecutive (debug-) output of that mode thus yields 0
for vsync. This simple fix also speeds up future invocations of
drm_mode_vrefresh(). While it is debatable whether this qualifies
as a -stable fix I'd apply it for consistency's sake;
drm_helper_probe_single_connector_modes() does the same thing already
for all probed modes.
