* Fix firelock prediction issues with periodic pulses of closing lights

For some reason this function was setting a time for the next state
which was triggering the door system to try to close the firelock.
This does not happen serverside because the function only fires from an
event called clientside apparently.
It appears to be an attempt to stop firelocks from closing instantly
that did not function properly, and I cannot discern any other purpose.
As such I have removed it.

* Remove redundant serverside check

This became redundant with commit 439a87f2
