During a simparse, virt_agents and eventlist need to be cleaned up

but not other virt_* tables. Thats coz the above two tables are not
truly virtual since they contain the vnode to which the event should
be sent to. My previous patch has been to use replace instead of
insert. Unfortunately, the tables get messed up with the same agent
having multiple entries where some of the entries were left behind
from the previous swapin.
