It is not allowed to call kfree_skb() from hardware interrupt
context or with interrupts being disabled. This patchset is
trying to add all skb to a free list, then free them after
spin_unlock_irqrestore() at once.

v2 -> v3:
  Update commit messages.

v1 -> v2:
  change subject prefix to "wifi: rtlwifi: ..."
