Test PCIbios.ventry against 0 to see if we found a PCIbios entry point,

not the 'entry' member.  The entry point is formed from both a base and
a relative entry point.  'entry' is that relative offset.  It is perfectly
valid to have an entry point with a relative offset of 0.  PCIbios.ventry
is the virtual address of the entry point that takes both 'base' and
'entry' into account, thus it is the proper variable to test to see if we
have an entry point or not.
