Remove the second check for a 64-bit BAR value on a 32-bit system in

pci_add_map().  First, this condition is already handled earlier in
the function.  Second, as written the check would never fire as the
'start' value was overwritten with a long value (rman_get_start() returns
long) before the comparison was done.
