Camera: Avoid recursive deadlock during device state changes

Device state change notifications are currently triggered while
holding 'mInterfaceMutex'. In case the camera provider tries
to add or remove a certain device/devices, then the provider
manager will try to recursively obtain the same 'mInterfaceMutex'.
Also avoid holding the 'mServiceLock' when notifying the
camera provider manager, access to its public interface
is already synchronized via 'mInterfaceMutex'.
