hal: Fix comparison of integers of different signs
The CameraHalManager::getCameraInfo() validates the camera id it receives from the camera service, and in doing so compares it with an unsigned integer, generating a compiler error: src/android/camera_hal_manager.cpp:121:9: error: comparison of integers of different signs: 'int' and 'unsigned int' [-Werror,-Wsign-compare] if (id >= numCameras() || id < 0) { ~~ ^ ~~~~~~~~~~~~ Fix this by turning the id into an unsigned int, as camera ids can't be negative. If a negative id is received from the camera service it will be converted to a large unsigned integer that will fail the comparison with numCameras().
