[iptables PATCH 1/2] ebtables: Fix rule listing with counters

[Phil Sutter]

This is a partial revert of commit 583b27eabcad6 ("ebtables-save: add -c
option, using xtables-style counters") which broke ruleset listing with
'--Lc' flag turned on:

| # ebtables-nft -L --Lc
| Bridge table: filter
|
| Bridge chain: INPUT, entries: 0, policy: ACCEPT
|
| Bridge chain: FORWARD, entries: 2, policy: ACCEPT
| -j foo
|  , pcnt = 0 -- bcnt = 0-j ACCEPT
|  , pcnt = 0 -- bcnt = 0
| Bridge chain: OUTPUT, entries: 0, policy: ACCEPT
|
| Bridge chain: foo, entries: 1, policy: RETURN
| -j ACCEPT
|  , pcnt = 0 -- bcnt = 0%

(That percentage sign means no newline after last line of output and
doesn't belong to ebtables-nft's output.)

Problem was that nft_bridge_print_rule() printed the counters after
nft_bridge_save_rule() had already printed the newline character.

Note also that there is no need to remove FMT_EBT_SAVE bit from 'format'
variable: It is set only by ebtables-nft-save which doesn't call
nft_bridge_print_rule().

Fixes: 583b27eabcad6 ("ebtables-save: add -c option, using xtables-style 
counters")
