hsr: set .netnsok flag

Browse Source 
[ Upstream commit 09e91dbea0aa32be02d8877bd50490813de56b9a ]

The hsr module has been supporting the list and status command.
(HSR_C_GET_NODE_LIST and HSR_C_GET_NODE_STATUS)
These commands send node information to the user-space via generic netlink.
But, in the non-init_net namespace, these commands are not allowed
because .netnsok flag is false.
So, there is no way to get node information in the non-init_net namespace.
