According to my reading of the code, this `assq` can never return
non-nil.

I think it was a left-over from many years ago when the byte-compiler
cuold generated code of the form (lambda (..) (byte-code ...)).

Strictly speaking we still occasionally generate such (byte-code ...)
thingies, but only in cases that don't apply here (e.g. it's not applied
for functions, see `byte-compile-out-toplevel`).
