ALSA: usb-audio: Add PM guard to Scarlett meter reads
The Scarlett Gen 1 meter callback reads the device without preventing
runtime suspend or disconnect. The transfer can fail when userspace
polls the volatile control after the device suspends.
Hold snd_usb_lock across the meter request. This matches the guarded
Forte and common mixer control paths in this file.
