USB: serial: digi_acceleport: add port lock nesting annotation
The driver takes the driver port lock of both the OOB port and the port
itself when setting the modem control signals, which confuses lockdep.
Mark the OOB port lock as belonging to a separate subclass to suppress
false positive lockdep deadlock warnings.
