We've met softlockup with "CONFIG_PREEMPT_NONE=y", when the target memcg
doesn't have any reclaimable memory.
It can be easily reproduced as below:
watchdog: BUG: soft lockup - CPU#0 stuck for 111s![memcg_test:2204]
CPU: 0 PID: 2204 Comm: memcg_test Not tainted 5.9.0-rc2+
shrink_slab_memcg() may iterate for a long time without resched if we
have many memcg with small amount of objects. Add cond_resched() to
avoid potential softlockup.
