net: arcnet: Do not call kfree_skb() under local_irq_disable()
[ Upstream commit 786c96e92fb9e854cb8b0cb7399bb2fb28e15c4b ]
It is not allowed to call kfree_skb() from hardware interrupt
context or with hardware interrupts being disabled.
So replace kfree_skb() with dev_kfree_skb_irq() under
local_irq_disable(). Compile tested only.
Fixes: 05fcd31cc472 ("arcnet: add err_skb package for package status feedback")
