  Log:
  Fix some entries in the locks static table of witness.
  In particular:
  - smp_tlb_mtx is no longer used, so it is axed.
  - smp rendezvous lock isn't really a leaf spin-mutex. Its bad placement in
    the table, however, has been the source of a false positive LOR reporting
    with the dt_lock.  However, smp rendezvous lock would have had sched_lock
    there for older lock, so it wasn't still a leaf lock.
  - allpmaps is only used in ia32 architecture, so it is inserted in the
    appropriate stub.
  
  Addictionally:
  - kse_zombie_lock is no longer present, so its definition is axed out.
  - zombie_lock doesn't need to have an exported symbol, so just let's it be
    declared as static.
