clang-15 warns about unqualified std cast calls:

../../test/camera/camera_reconfigure.cpp:101:24: error: unqualified call to 'std::move' [-Werror,-Wunqualified-std-cast-call]
                        requests_.push_back(move(request));
                                            ^
                                            std::

Fix it.
