  Changed paths:
    M ofproto/pktbuf.c

  Log Message:
  -----------
  pktbuf: Always initialize '*bufferp' even when 'pb == NULL'.

Otherwise if a service connection (which does not have buffers) attempts
to use buffers, '*bufferp' will be uninitialized, which can cause a
segfault in the caller.

Found using OFtest configured to use service (active rather than passive)
connections.
