From: Geliang Tang <[email protected]>
This patch renames mptcp_pm_nl_get_addr_dumpit() as a dedicated in-kernel
netlink PM dump addrs function mptcp_pm_nl_dump_addr(), and invoke a newly
added wrapper mptcp_pm_dump_addr() in mptcp_pm_nl_get_addr_dumpit().
Invoke in-kernel PM dump addrs function mptcp_pm_nl_dump_addr() or
userspace PM dump addrs function mptcp_userspace_pm_dump_addr() based on
whether the token parameter is passed in or not in the wrapper.
