Peter Zijlstra d846b69dc7 rcu: Fix rcu_dynticks_curr_cpu_in_eqs() vs noinstr 
[ Upstream commit 74aece72f9 ]

  vmlinux.o: warning: objtool: rcu_nmi_enter()+0x36: call to __kasan_check_read() leaves .noinstr.text section

noinstr cannot have atomic_*() functions in because they're explicitly
annotated, use arch_atomic_*().

Fixes: 2be57f7328 ("rcu: Weaken ->dynticks accesses and updates")
