ASoC: rt7*-sdw: harden jack_detect_handler

Browse source

Realtek headset codec drivers typically check if the card is
instantiated before proceeding with the jack detection.

The rt700, rt711 and rt711-sdca are however missing a check on the
card pointer, which can lead to NULL dereferences encountered in
driver bind/unbind tests.
