Geza Lore d42a2d6494 Fix V3Gate crash on circular logic
The recent patch to defer substitutions on V3Gate crashes on circular
logic that has cycle length >= 3 with all inlineable signals (cycle
length 2 is detected correctly and is not inlined). Fix by stopping
recursion at the loop-back edge.

Fixes #3543
