4.2-stable review patch. If anyone has any objections, please let me know.

From: Dragos Tatulea <dragos@endocode.com>
[ Upstream commit 24cb7055a3066634a0f3fa0cd6a4780652905d35 ]
rtnl_fdb_dump always expects an index to be returned by the ndo_fdb_dump op, but when CONFIG_NET_SWITCHDEV is off, it returns an error.
Fix that by returning the given unmodified idx.
A similar fix was 0890cf6cb6ab ("switchdev: fix return value of switchdev_port_fdb_dump in case of error") but for the CONFIG_NET_SWITCHDEV=y case.
