macvlan: use the right RCU api
Make sure we use proper API to fetch dev->rx_handler_data,
instead of ugly casts.
Rename macvlan_port_get() to macvlan_port_get_rtnl() to document fact
that we hold RTNL when needed, with lockdep support.
This removes sparse warnings as well (CONFIG_SPARSE_RCU_POINTER=y)
CHECK drivers/net/macvlan.c
