From: Geliang Tang <tanggeliang@kylinos.cn>

Now mptcp_pm_is_backup() can directly invoke get_priority() interface
through "ops" of "msk->pm". Instead of using mptcp_pm_is_userspace()
to check which is_backup() helper to invoke.

Then mptcp_pm_nl_is_backup() and mptcp_userspace_pm_is_backup() helpers
can be static.
