[PATCH] pwc bug fix

The pwc chainsaw session left some setups not working. There is a
sanity check on compression buffers that simply isn't right any more as
we never allocate one.

This doesn't address the email and other changes. I'll do those
tomorrow if I get time, but it is the minimal fix for the code and basic
feature set.
