Cuong Manh Le 844e1fc6f1 cmd/compile: make typecheckaste correctly report invalid use of "..."
Currently, when "..." argument is passed to non-variadic function, the
compiler may skip that check, but continue checking whether the number
of arguments matches the function signature.

That causes the sanity check which was added in CL 255241 trigger.

Instead, we should report an invalid use of "...", which matches the
behavior of new type checker and go/types.

Fixes #45913
