Revert "Force voice path when recording audio during call"

This change breaks apps that listen for callstate changes and
immediately open an input stream. The app will open an input stream
before the callstate changes, causing the stream to be open on the voice
path that immediately closes.

This reverts commit 0d2d286a5bbf912a5e1352d146147a3457fe5cb5.
