Subject: [PATCH net-next 2/2] net: openvswitch: Constify static struct genl_ops

The only usage of these is to assign their address to the ops field in
the genl_family struct, which is a const pointer, and applying
ARRAY_SIZE() on them. Make them const to allow the compiler to put them
in read-only memory.
