USB: option: fix when the driver is loaded incorrectly for some Huawei devices.

commit 58c0d9d70109bd7e82bdb9517007311a48499960 upstream.

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.
