Eric Dumazet d50b11c21f net: usb: sr9700: stop lying about skb->truesize ...

[ Upstream commit 05417aa9c0c038da2464a0c504b9d4f99814a23b ]

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

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

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") and 4ce62d5b2f7a ("net: usb: ax88179_178a:
stop lying about skb->truesize")
