vspd: Remove simnet params.

Simnet params were added in the very first commit of vspd purely because
of copy/pasting from another project.

vspd has never actually been tested on simnet, so its possible
(probable) that it won't even operate correctly without additional dev
work. If we want simnet to be a properly supported network it can be
re-added and tested in the future.
