Fixed unsafe lock upon safe media volume
Safe media volume uses lock as Integer.
But it is not safe since the Integer value is changed.
disableSafeMediaVolume()
synchronized (mSafeMediaVolumeState) // step. 1
setSafeMediaVolumeEnabled()
mSafeMediaVolumeState = SAFE_MEDIA_VOLUME_ACTIVE // step. 2
...
onSetStreamVolume(mPendingVolumeCommand.mStreamType, // step.4
-> mPendingVolumeCommand is set as null by step.3
-> it causes NPE and reboot
------------
setStreamVolume()
synchronized (mSafeMediaVolumeState)
-> mSafeMediaVolumeState was changed by step.2
-> so that it would go next step
mPendingVolumeCommand = null; // step. 3
Test: Build Pass, manual test, change volume
