mptcp: consolidate rcv space init

Browse source

MPTCP uses several calls of the mptcp_rcv_space_init() helper to
initialize the receive space, with a catch-up call in
mptcp_rcv_space_adjust().

Drop all the other strictly not needed invocations and move constant
fields initialization at socket init/reset time.

This removes a bit of complexity from mptcp DRS code. No functional
changes intended.
