net: use correct this_cpu primitive in dev_recursion_level
syzbot reports:
BUG: using __this_cpu_read() in preemptible code:
caller is dev_recursion_level include/linux/netdevice.h:3052 [inline]
__this_cpu_preempt_check+0x246/0x270 lib/smp_processor_id.c:47
dev_recursion_level include/linux/netdevice.h:3052 [inline]
ip6_skb_dst_mtu include/net/ip6_route.h:245 [inline]
I erronously downgraded a this_cpu_read to __this_cpu_read when
moving dev_recursion_level() around.
