Subject: [PATCHv2 iproute2] bridge/mdb: fix missing new line when show bridge mdb

The bridge mdb show is broken on current iproute2. e.g.
]# bridge mdb show
34: br0  veth0_br  224.1.1.2  temp 34: br0  veth0_br  224.1.1.1  temp

After fix:
]# bridge mdb show
34: br0  veth0_br  224.1.1.2  temp
34: br0  veth0_br  224.1.1.1  temp

v2: use json print lib as Stephen suggested.

Reported-by: Ying Xu <yinxu@...hat.com>
Fixes: c7c1a1ef51aea ("bridge: colorize output and use JSON print library")
