drm/radeon/kms: fix bugs in ddc and cd path router code
This is a follow on to: 2b5b1d7da9583484b3a9e7e375a90ca0e8ca07c2 (drm/radeon/kms: add support for clock/data path routers) That patch completed mux support for ddc and cd line routing between connectors. This patch fixes an indexing typo that was resulting in the atom bios router objects not always being walked, ensures the validity entries for the reused router structure are reset for every connector object walked, and corrects the masking operations used to update the mux control bits.
