Remove erroneous DCHECK related to expression classifiers

Remove erroneous DCHECK related to expression classifiers

It seems that I forgot to remove the DCHECK when refactoring this
function, even though the comment had it right.  It also seems that
this is hard to trigger.  The minimal example I found, after fuzzer's
bug, was:

   eval, x[eval]
