vlserver: Use correct base value when replacing

When we're removing existing address entries the code calculates
a base and index value for each entry that we're removing an address
from. However, it then _uses_ a previously calculated base value,
with the new index. This works fine if the old base and the new base
match, but if they don't, chaos will ensue.

Fix to always use matched base and index pairs.
