MediaFocusControl: Do not grant audio focus if notification stream is 0

Previously audio focus would be granted regardless of notification volume, meaning
that if notifications are muted the media stream would still be dimished for focus.
By checking if STREAM_NOTIFICATION is 0 and if a notification stream is
requesting focus, this no longer an issue.

PS1: Initial implement
PS2: Better implement in MediaFocusControl
PS3: Whitespace
