Hirokazu Honda 67e791373d libcamera: device_enumerator: Remove unnecessary rvalue references
There are std::unique_ptr rvalue reference arguments. They are
intended to pass the ownership to the functions. In the case,
it is right to let the argument be std::unique_ptr value and
pass by std::move().
