net: arcnet: Do not call kfree_skb() under local_irq_disable() 

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: 05fcd31cc4 ("arcnet: add err_skb package for package status feedback")
