net: lantiq_etop: don't free skb when returning NETDEV_TX_BUSY
[ Upstream commit 9c1eaa27ec599fcc25ed4970c0b73c247d147a2b ]
The ndo_start_xmit() method must not free skb when returning
NETDEV_TX_BUSY, since caller is going to requeue freed skb.
Fixes: 504d4721ee8e ("MIPS: Lantiq: Add ethernet driver")
