Eric Dumazet b51177e40e net: usb: ax88179_178a: stop lying about skb->truesize
[ Upstream commit 4ce62d5b2f7aecd4900e7d6115588ad7f9acccca ]

Some usb drivers try to set small skb->truesize and break
core networking stacks.

In this patch, I removed one of the skb->truesize overide.

I also replaced one skb_clone() by an allocation of a fresh
and small skb, to get minimally sized skbs, like we did
in commit 1e2c611723 ("net: cdc_ncm: reduce skb truesize
in rx path")

Fixes: f8ebb3ac88 ("net: usb: ax88179_178a: Fix packet receiving")
