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
drivers/net/macvlan.c:706:37: warning: cast removes address space of expression
drivers/net/macvlan.c:775:16: warning: cast removes address space of expression
