usb: serial: silence all non-critical read errors
If a USB serial device is unplugged while there is an active program
using the device it may spam the logs with -EPROTO (71) messages as it
attempts to retry.
Most serial usb drivers (metro-usb, pl2303, mos7840, ...) only output
these messages for debugging. The generic driver treats these as
errors.
Change the default output for the generic serial driver from error to
debug to silence these non-critical errors.
