vvp: Don't schedule initial value propagation for net array ports 

An initial value propagation should only be scheduled for variable array
ports, but not for net array port since those do not contain any values.

This got accidentally broken when fixing support for 2-state variable
array ports.

Add a check that only does the initial value propagation if the port is for
a variable array.

Fixes: 0eb01fff1e ("vvp: Fix initial value propagation for 2-state non-automatic arrays")
