hal: Fix comparison of unsigned integer < 0
The CameraHalManager::getCameraInfo() validates the camera id it receives from the camera service, and in doing so generates a compiler error with gcc as the id is an unsigned integer and can never be negative: ../src/android/camera_hal_manager.cpp: In member function ‘CameraProxy* CameraHalManager::open(unsigned int, const hw_module_t*)’: ../src/android/camera_hal_manager.cpp:89:9: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits] if (id < 0 || id >= numCameras()) { Fix it by removing the unneeded comparison.
