lcr/es51919: clean but don't free dev context in cleanup callback

The es51919_serial_clean() routine is called by std_dev_clear_with_callback().
Common code unconditionally frees the 'priv' part. The cleanup callback only
shall release descending resources which are local to the callee and opaque
to the caller.

This fixes a double free error. Tested with PeakTech 2170.
