mptcp: sched: remove mptcp_sched_data

Browse source 
This is a follow-up of commit b68b106b0f ("mptcp: sched: reduce size
for unused data"), now removing the mptcp_sched_data structure.

Now is a good time to do that, because the previously mentioned WIP work
has been updated, no longer depending on this structure.
