Apply default selected device to all presets 

When system is initialized, or when audio device is
connected/disconnected, the default active input device returned back
from AudioPolicyManager does not apply to all all capture presets.

This leads to an issue that the selected device shown in UI does not
match the real device used in some presets (e.g. recording), which
makes users confused. This CL fixes this problem by applying the
default selected device to all presets.
