USB: option: fix when the driver is loaded incorrectly for some Huawei devices.
When huawei datacard with PID 0x14AC is insterted into Linux system, the present kernel will load the "option" driver to all the interfaces. But actually, some interfaces run as other function and do not need "option" driver. In this path, we modify the id_tables, when the PID is 0x14ac ,VID is 0x12d1, Only when the interface's Class is 0xff,Subclass is 0xff, Pro is 0xff, it does need "option" driver.
