CRAS: iodev_list - Check if pinned device is open already
cras_iodev can be opened and accessed by audio_thread
in two ways:
(1) UI enables an input/output audio node.
(2) An application creates a stream that pins to specific audio node.
This change adds a function to ask if the given device is already
in use by the audio_thread. It can be used to avoid unecessary
calls and possible multi thread access to iodev.
