Built-in mic is not used when USB mic is disconnected

In some cases when the USB microphone is disconnected,
audio stack does not switch to the built-in microphone.
It gets stuck in a state where it still recognizes the
USB mic is still connected. Current device removal
implementation only considers USB output devices such
as headset. The same process should be used for input
USB devices (microphone).
