Currently we allocate the MPTCP master socket at accept time.

The above makes mptcp_accept() quite complex, and requires checks is several
places for NULL MPTCP master socket.

These series simplify the MPTCP accept implementation, moving the master socket
allocation at syn-ack time, so that we drop unneeded checks with the follow-up
patch.

v1 -> v2:
- rebased on top of 2398e3991bda7caa6b112a6f650fbab92f732b91

  mptcp: create msk early
  mptcp: drop unneeded checks
