Subject: [PATCH net-next 0/2] mptcp: simplify mptcp_accept()

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.

Note: patch 2/2 will conflict with net commit 2398e3991bda ("mptcp: always 
include dack if possible."). If the following will help, I can send a rebased
version of the series after that net is merged back into net-next.

  mptcp: create msk early
  mptcp: drop unneeded checks
