ALSA: usb-audio: Add PM guards to US-16x08 transfers
The TASCAM control helpers submit vendor requests without preventing
runtime suspend or disconnect. This affects mixer writes and the
volatile meter path.
Protect both send and receive helpers with snd_usb_lock. Acquire the PM
guard before chip->mutex in the receive path so autoresume cannot invert
the mutex order.
