Patch to always reset validity entries in reused router structure instead of
just for connectors with attached router objects

Hey Alex,

It didn't seem like it should be too hard to figure out where that router was
being picked up for the LVDS port, so I had a look through the code and came up
with the above patch.

With this patch, the connector information looks correct now

Unfortunately though, even with this patch, I'm still getting that weired cross
over of the HDMI onto the DVI (that is, the monitor attached to the HDMI port
is still listed under both HDMI-0 and DVI-0, and enabled by default on the
DVI-0).

Cheers!  -Tyson
