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.
