- Fix braino introduced in rev. 1.17, unlike the X1032A (HME-ISP1040-combo)

Browse Source 
and the X1034A (quad HME; QFE) cards the X1033A (single HME) don't have a
  PCI-PCI-bridge so we can't rely on the PCI slot number being useable as
  index for the network address to read from the VPD on the latter. Use
  the end tag to determine whether it is a QFE VPD with 4 NAs and only use
  the slot number as index in this case.
- Remove a useless check.
