Merge tcp_subr.c:1.251 from HEAD to RELENG_6:

  Fix race conditions on enumerating pcb lists by moving the initialization
  (and where appropriate the destruction) of the pcb mutex to the
  init/finit functions of the pcb zones.  This allows locking of the pcb
  entries and race condition free comparison of the generation count.
  Rearrange locking a bit to avoid extra locking operation to update the
  generation count in in_pcballoc().  (in_pcballoc now returns the pcb
  locked)

  I am planning to convert pcb list handling from a type safe to a
  reference count model soon.  (As this allows really freeing the PCBs)

This was missed in jhb's earlier MFC, and lead to a panic when creating
TCP sockets.
