drivers: usb: Mark function as static in metro-usb.c

Browse source

Mark function metrousb_is_unidirectional_mode() in serial/metro-usb.c
because it is not used outside this file.

This eliminates the following warning in serial/metro-usb.c:
drivers/usb/serial/metro-usb.c:57:12: warning: no previous prototype for ‘metrousb_is_unidirectional_mode’ [-Wmissing-prototypes]
