UPSTREAM: net: usb: ax88179_178a: stop lying about skb->truesize

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 1e2c61172342 ("net: cdc_ncm: reduce skb truesize
in rx path")

Fixes: f8ebb3ac881b ("net: usb: ax88179_178a: Fix packet receiving")
