Subject: [PATCH] ebtables: Dump atomic waste

With ebtables-nft.8 now educating people about the missing
functionality, get rid of atomic remains in source code. This eliminates
mostly comments except for --atomic-commit which was treated as alias of
--init-table. People not using the latter are probably trying to
atomic-commit from an atomic-file which in turn is not supported, so no
point keeping it.
