drochner 27098b1199 restructure the diskless NFS boot code to keep track of the used
interface and the address allocated, to roll everything back if the
mount fails:
-put an interface pointer into "struct nfs_diskless" to have it
 available for cleanup, don't pass it around anymore where the
 "struct nfs_diskless" is already passed
-add a "cleanup" function which shuts the interface down
-in the protocol-specific parts, either return with "everything
 ready" or "completely shut down"
-use common functions for interface initialization and shutdown
-add a function to delete all routes associate to an interface
 (why is this necessary and not done by ~IFF_UP?)
