John Baldwin 835a748f30 - Change extra sanity checks in cpu_switch() to be conditional on INVARIANTS
instead of DIAGNOSTIC.
- Remove the p_wchan check as it no longer applies since a process may be
  switched out during CURSIG() within msleep() or mawait().
- Remove an extra sanity check only needed during the early SMPng work.
