wifi: rtl8xxxu: don't call dev_kfree_skb() under spin_lock_irqsave()
stable inclusion from stable-v5.10.173 commit 75f4eed70a519717ea91347370207e57b97a632f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8BFR3 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=75f4eed70a519717ea91347370207e57b97a632f -------------------------------- [ Upstream commit 4c2005ac ] It is not allowed to call kfree_skb() or consume_skb() from hardware interrupt context or with hardware interrupts being disabled. It should use dev_kfree_skb_irq() or dev_consume_skb_irq() instead. The difference between them is free reason, dev_kfree_skb_irq() means the SKB is dropped in error and dev_consume_skb_irq() means the SKB is consumed in normal. In this case, dev_kfree_skb() is called to free and drop the SKB when it's shutdown, so replace it with dev_kfree_skb_irq(). Compile tested only.
