sched/membarrier: fix missing local execution of ipi_sync_rq_state()

stable inclusion
from stable-5.10.24
commit 68b4378d910e1716c91ad288e8683354d282f5fa
bugzilla: 51348

--------------------------------

commit ce29ddc4 upstream.

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().
