bridge: netlink: call br_changelink() during br_dev_newlink()
[ 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.
Fixes: 133235161721 ("bridge: implement rtnl_link_ops->changelink")
