[PATCH mptcp-next v3 1/3] mptcp: token kunit: set protocol

["Matthieu Baerts (NGI0)" <matttbe@kernel.org>]

As it would be done when initiating an MPTCP sock.

This is not strictly needed for this test, but it will be when a later
patch will check if the right protocol is being used when calling
mptcp_sk().
