Fix build, if CONFIG_SYSCTL is disabled:

WARNING: net/built-in.o(.text+0xa550f): Section mismatch in reference
from the function mptcp_pm_undo() to the variable
.init.data:mptcp_pm_proc_ops
The function mptcp_pm_undo() references
the variable __initdata mptcp_pm_proc_ops.
This is often because mptcp_pm_undo lacks a __initdata
annotation or the annotation of mptcp_pm_proc_ops is wrong.
