[VLAN]: Convert name-based configuration functions to struct netdevice *
Move the device lookup and checks to the ioctl handler under the RTNL and change all name-based interfaces to take a struct net_device * instead. This allows to use them from a netlink interface, which identifies devices based on ifindex not name. It also avoids races between the ioctl interface and the (upcoming) netlink interface since now all changes happen under the RTNL. As a nice side effect this greatly simplifies error handling in the helper functions and fixes a number of incorrect error codes like -EINVAL for device not found.
