The mask must not be zero otherwise the matching condition will never
be true: ((val & mask) == set).

Bit 7 of the pci device header type is an indicator of multi-function
devices, so needs to be masked when examining the bridge type.
Thanks go to Chih-Pin Wu for finding the bug and its fix.

This reverts commit 2bda5b733bb12854760750c08138db95e77aea0c.
It actually conflicts with 9ba94caf57e3a8c3e9c6f3f5f068f4a7a7b3ff9d
which came earlier, but I didn't catch it probably because I did a blind
rebase before pushing.
When reading bridge bus info, we may need to read out the current bridge
info if the PCI bridge private is uninitialized, so remove the check at
the top that would always short circuit the case where the priv was
still 0.

If, for whatever reason, we weren't able to read bridge data (therefore
leaving bridge.pci or bridge.pcmcia empty), we shouldn't try to look at
the bus data inside the pci/pcmcia struct.
