Timothée COCAULT 63137bc588 netfilter: ebtables: Fixes dropping of small packets in bridge nat 
Fixes an error causing small packets to get dropped. skb_ensure_writable
expects the second parameter to be a length in the ethernet payload.=20
If we want to write the ethernet header (src, dst), we should pass 0.
Otherwise, packets with small payloads (< ETH_ALEN) will get dropped.

Fixes: c1a8311679 ("netfilter: bridge: convert skb_make_writable to skb_ensure_writable")
