Stefan Wahren 2be27d444f net: lan78xx: Fix race in tx pending skb size calculation ...

commit dea39aca1d upstream.

The skb size calculation in lan78xx_tx_bh is in race with the start_xmit,
which could lead to rare kernel oopses. So protect the whole skb walk with
a spin lock. As a benefit we can unlink the skb directly.

This patch was tested on Raspberry Pi 3B+
