ALSA: usb-audio: Replace manual mutex/spinlock with guard()
This is another code cleanup by replacing the manual mutex or spinlock
with guard() macros. usb_audio_disconnect() is slightly refactored
(split to another function) to apply guard() cleanly, but the rest are
rather straightforward conversions.
No functional changes but only code refactoring.
