If the first loop is removed, there is some situation the second one
can't handle.
e.g.
a quirk table has:
{0x12, 0x9xxxxxxx},
{0x14, 0x9xxxxxxx},
{0x21, 0x02xxxxxx}
while a machine only has
{0x12, 0x9xxxxxxx},
{0x21, 0x02xxxxxx}
and the NID 0x14 on the machine is a [Vendor Defined Widget] instead of
a [pin complex].
In this situation, only the first loop can detect they are not matching.

Hui.
