In order to find all the processes in a system dump, kvm_deadproc
traverses the 'allproc', 'deadproc' and 'zombproc' lists.
However the current kernel links 'deadproc' through the
p_hash field - such processes are actually on 'zombproc' as well.
So traversing 'deadproc' is unnecessary as well as being wrong.
Note that the code has always failed to return anything found
on 'deadproc' because dcnt isn't allowed for during the read
of the 'zombproc' list, nor is it included in the returned
Remove the effect of delta 1.27 of libkvm/kvm_proc.c
