kernel - Fix proc_reparent() race/assertion panic

* Fix proc_reparent() race/assertion panic.  p_pptr changes can race,
  and the procedure had an assertion for the case.  Recode the procedure
  to retry on a mismatch instead of assert.

* Also move the old-parent-wakeup code into the procedure so it is
  properly executed in all cases.
