ALSA: usb-audio: Fix build with CONFIG_INPUT=n

[ Upstream commit d0630a0b80c08530857146e3bf183a7d6b743847 ]

The recent addition of DualSense mixer quirk relies on the input
device handle, and the build can fail if CONFIG_INPUT isn't set.
Put (rather ugly) workarounds to wrap with IS_REACHABLE() for avoiding
the build error.
