mptcp: add token for get-addr in yaml

This patch adds token parameter together with addr in get-addr section in
mptcp_pm.yaml, then use the following commands to update mptcp_pm_gen.c
and mptcp_pm_gen.h:

./tools/net/ynl/ynl-gen-c.py --mode kernel \
        --spec Documentation/netlink/specs/mptcp_pm.yaml --source \
        -o net/mptcp/mptcp_pm_gen.c
./tools/net/ynl/ynl-gen-c.py --mode kernel \
        --spec Documentation/netlink/specs/mptcp_pm.yaml --header \
        -o net/mptcp/mptcp_pm_gen.h
