Subject: [PATCH v2 net] net: sonic: replace dev_kfree_skb in sonic_send_packet

sonic_send_packet will be processed in irq or non-irq 
context, so it would better use dev_kfree_skb_any
instead of dev_kfree_skb.

Fixes: d9fb9f384292 ("*sonic/natsemi/ns83829: Move the National Semi-conductor drivers")
