ALSA: usb-audio: Roll back quirk control caches on write errors

Several mixer quirk callbacks cache the requested
control value in kcontrol->private_value before
issuing a single vendor or class write.

Their paired get and resume paths consume that cache
directly, so a failed write currently leaves software
state changed even though the update did not succeed.
That can make later reads report a value the device
never accepted and can replay the stale cache on resume.

Restore the previous cached value on failure in
the Audigy2NX LED, Emu0204 channel switch,
Xonar U1 output switch, Native Instruments controls,
FTU effect program switch, and Sound Blaster E1 input source switch.
