[ebtables-compat PATCH 2/2] nft-bridge: fix printing of inverted protocols, addresses

[Arturo Borrero Gonzalez <arturo.borrero.glez@xxxxxxxxx>]

Previous to this patch, no '!' is printed in payload comparisions.
This patch solves it, so we can print for example inverted protocols:

 % ebtables-compat -L
[...]
-p ! 0x800 -j ACCEPT
