x/tools/gopls: Rename: "no type for %T" panic in satisfy

[adonovan]

#!stacks
"runtime.gopanic" && "satisfy.(*Finder).expr:+168"

Issue created by stacks.

This means satisfy was called on ill-typed code. As with #71538, the long-term remedy here is to get rid of the satisfy package and use #70638 instead.
