setInternalRegsDelayFree only for candidate lclVars

[kunalspathak]

In #58914 , we partially fixed the #58899, but it should have taken into account it only for candidate lclVars. Without this, we would end up having a delayFree on last use and when we see the new refposition, we would assert because there was a pending delayRegFree without reference.

Fixes: #61579
