Mathieu Desnoyers ce29ddc47b sched/membarrier: fix missing local execution of ipi_sync_rq_state() 
The function sync_runqueues_membarrier_state() should copy the
membarrier state from the @mm received as parameter to each runqueue
currently running tasks using that mm.

However, the use of smp_call_function_many() skips the current runqueue,
which is unintended. Replace by a call to on_each_cpu_mask().

Fixes: 227a4aadc7 ("sched/membarrier: Fix p->mm->membarrier_state racy load")
