Subject: bridge: netlink: call br_changelink() during br_dev_newlink()

From: Ivan Vecera <redacted>


[ Upstream commit b6677449dff674cf5b81429b11d5c7f358852ef9 ]

Any bridge options specified during link creation (e.g. ip link add)
are ignored as br_dev_newlink() does not process them.
Use br_changelink() to do it.
