Subject: net: Handle unregister properly when netdev namespace change fails.
X-Git-Tag: omap-for-v4.1/fixes-rc1~306^2~28

net: Handle unregister properly when netdev namespace change fails.

If rtnl_newlink() fails on it's call to dev_change_net_namespace(), we
have to make use of the ->dellink() method, if present, just like we
do when rtnl_configure_link() fails.
