wifi: wl3501_cs: don't call kfree_skb() under spin_lock_irqsave()

[ Upstream commit dc04d39f82a91ba0fc4397f0a978355bb7c804a5 ]

It is not allowed to call kfree_skb() from hardware interrupt
context or with interrupts being disabled. So replace kfree_skb()
with dev_kfree_skb_irq() under spin_lock_irqsave(). Compile
tested only.
