kernel: fix pexit() Waitmsg memory leak.
when a process got forked with RFNOWAIT, its p->parent will still
point to the parent process, but its p->parentpid == 0.
this causes the "parent still alive" check in pexit to get confused
as it only checked p->pid == up->parentpid. this condition is *TRUE*
in the case of RFNOWAIT when the parent process is actually dead
(p->pid == 0) so we attached the wait structure to the dead parent
leaking the memory.
