V4L/DVB (10125): em28xx: Don't do AC97 vendor detection for i2s audio devices

Browse Source 
The current code was trying to query the AC97 registers for the vendor
information even if it was clearly not a AC97 audio device (resulting in errors
in the dmesg output).  This was due to a bug in the way we did the check.
