kernel - Fix multi-threaded coredump

* Recent commits to freeze threads on a coredump introduced a bug
  where threads entering a wait state could stall the coredump
  indefinitely.

* Fix by counting such threads as being stopped before entering the
  wait state, allowing the coredump to proceed.  Do not try to issue
  an early signal which could disrupt the state the coredump is trying
  to save.
