From: Geliang Tang <tanggeliang@kylinos.cn>

Now mptcp_subflow_set_scheduled() is no longer used in BPF, but only in
kernel. A new mptcp_subflow_set_scheduled() helper will be implemented
in BPF specifically for use with BPF. To avoid compilation errors due
to duplicate names, this function is made inline in kernel and moved into
protocol.h.
