bankd: createMapping should implicitly delete existing mappings

As explained in OS#4278, a remsim-bankd currently doesn't recover after
a remsim-server resetart, since old mappings remain in the bankd, and
the server has no chance of removing them.

To avoid this problem, a createMapping now always implicitly removes
any existing mapping that may exist for the given bankdSlot.
