rcu: Suppress __mpol_dup() false positive from RCU lockdep
Common code is used during task creation and after the task has
started running. RCU protection is not needed during task
creation because no other CPU has access to the
under-construction task. Provide the RCU protection anyway to
suppress the false positive, as there does not appear to be a
good way for the common code to recognize that the task is only
accessible to the CPU creating it.
