description:
Fix sense of conditional in previous.

I must have tested (cold ? (void *)1 : curlwp) but then decided,
after testing, to replace cold by !curcpu_available() -- thinking
that would be a safe change to make, except I forgot to either write
the ! or change the sense of the conditional.  OOPS.
