Cássio Gabriel a9224f26b7 ALSA: usb-audio: Fix Audio Advantage Micro II SPDIF switch 
snd_microii_spdif_switch_put() returns 0 when the requested
vendor register value differs from the cached one.

This comparison was inverted by the resume-support conversion,
so real SPDIF switch toggles are ignored while no-op writes still
issue SET_CUR and report success.

Return early only when the requested value matches the cached one.

Fixes: 288673beae ("ALSA: usb-audio: Add resume support for MicroII SPDIF ctls")
