Hi Takashi,

This quirk patch is quite straight forward, but when I was working on it
I discovered something else: the pin_quirk actually overrides the
regular quirk (there is a vendor quirk for HP in the other quirk table).

While the optimal order would be 
 1) ssid specific quirks
 2) pin quirks
 3) vendor specific quirks
...this is not that easy to accomplish given the current structure given that
1) and 3) is in one table and 2) is in another table. But before I go ahead
and make any changes, I wanted to hear your thoughts about it.
