Camera: remove the camera device version check during statusCallback

Since HAL1 support has been removed, we don't need to check the device
version in statusCallback any more.

This has the good side effect of fixing a bug during hotplug camera
removal. A hotplug camera may be removed from ProviderInfo::mDevices,
and when getDeviceVersion() is called, the camera ID cannot be found.

Test: Camera CTS
