audio: fix deadlock with echo reference access There is a problem with mutex acquisition order when removing or adding an echo reference from do_input_standby_l() or start_input_stream(): the output stream mutex is acquired after the audio device mutex creating a potential cross deadlock as the required order is output stream mutex then audio device mutex. Bug: 17830596. Change-Id: I465f4eeb1f1f2e76d6cc3d685d96e4758c6bc473
