[MACVLAN]: Setting macvlan_handle_frame_hook to NULL when rtnl_link_register() fails.

Browse Source 
In drivers/net/macvlan.c, when rtnl_link_register() fails in
macvlan_init_module(), there is no point to set it (second time in
this method) to macvlan_handle_frame; macvlan_init_module() will
return a negative number, so instead this patch sets
macvlan_handle_frame_hook to NULL.
