This check should actually be IsTabAudioMutingFeatureEnabled (but it's still
useful to mention the flag in the error message; perhaps aliasing muteSwitch
isn't that useful though)

It's polite to mention the tab ID, also, better details than "cannot update mute
state" would be nice, i.e. why it failed. Looks like it's because we're either
RECORDING or CAPTURING:

https://code.google.com/p/chromium/codesearch#chromium/src/chrome/browser/ui/...

I think it's enough to just say "Cannot update mute state for tab %d, tab has
audio or video currently being captured".
