Peter Xu 05b7ec1890 migration/multifd: Rename p->num_packets and clean it up 
This field, no matter whether on src or dest, is only used for debugging
purpose.

They can even be removed already, unless it still more or less provide some
accounting on "how many packets are sent/recved for this thread".  The
other more important one is called packet_num, which is embeded in the
multifd packet headers (MultiFDPacket_t).

So let's keep them for now, but make them much easier to understand, by
doing below:

  - Rename both of them to packets_sent / packets_recved, the old
  name (num_packets) are waaay too confusing when we already have
  MultiFDPacket_t.packets_num.

  - Avoid worrying on the "initial packet": we know we will send it, that's
  good enough.  The accounting won't matter a great deal to start with 0 or
  with 1.

  - Move them to where we send/recv the packets.  They're:

    - multifd_send_fill_packet() for senders.
    - multifd_recv_unfill_packet() for receivers.
