Subject: [media] wm8775: fix broken audio routing

commit 3af41a337a5b270de3e65466a07f106ad97ad0c6 upstream.

Commit 5aa9ae5ed5d449a85fbf7aac3d1fdc241c542a79 inverted the mute control
state test in s_routing which caused the audio routing to fail. This broke
ivtv support for the Hauppauge video/audio input bracket (which adds additional
video and audio inputs) all the way back in kernel 2.6.36.
This fix fixes the condition and it also removes a nonsense check on the
balance control.
