[PATCH v4 net-next 2/7] net: dsa: be louder when a non-legacy FDB operation fails

From: Vladimir Oltean <vladimir.oltean@nxp.com>

The dev_close() call was added in commit c9eb3e0f8701 ("net: dsa: Add
support for learning FDB through notification") "to indicate inconsistent
situation" when we could not delete an FDB entry from the port.

bridge fdb del d8:58:d7:00:ca:6d dev swp0 self master

It is a bit drastic and at the same time not helpful if the above fails
to only print with netdev_dbg log level, but on the other hand to bring
the interface down.

So increase the verbosity of the error message, and drop dev_close().
