libpayload: Add UNKNOWN_SPEED to usb_speed enum
xhci_rh_port_speed return -1 if the port is disabled. The usb_speed enum
is unsigned so this results in a positive value which implies success.
Adding a -1 to the enum will make it signed so the >= 0 check will work
correctly.
BUG=b:76831439
TEST=verified on grunt that -1 is returned when port is disabled.
