AudioService: fix cross deadlock when accessing audio mode

Do not recompute the requested audio mode by calling getMode()
(which takes mDeviceBroker.mSetModeLock) when only the currently
applied mode is needed to make a decision.

This avoids from worrying about cross deadlocks between
mDeviceBroker.mSetModeLock and mDeviceBroker.mDeviceStateLock
in all code paths that read current audio mode.

Store current mode in an atomic integer.
