Subject: [PATCH iproute2] bridge: mdb: restore text output format

While I fixed the mdb json output, I did overlook the text output.
This patch returns the original text output format:
 dev <bridge> port <port> grp <mcast group> <temp|permanent> <flags> <timer>
Example (old format, restored by this patch):
 dev br0 port eth8 grp 239.1.1.11 temp

Example (changed format after the commit below):
 23: br0  eth8  239.1.1.11  temp

We had some reports of failing scripts which were parsing the output.
Also the old format matches the bridge mdb command syntax which makes
it easier to build commands out of the output.

Fixes: c7c1a1ef51ae ("bridge: colorize output and use JSON print library")

I know text output isn't considered API, but there are scripts out there
which rely on the format or at least on the old strings/values to be
present.
