Add lock when adjusting suggested stream volume.

When adjusting suggested stream volume, we may set the stream type
according to mVolumeControlStream, which could be changed by other
thread. To avoid getting stream type -1, which cause crash when checking
stream type, add a lock request in adjustSuggestedStreamVolume.
