netlink: remove type-unsafe validation_data pointer
In the netlink policy, we currently have a void *validation_data
that's pointing to different things:
* a u32 value for bitfield32,
* the netlink policy for nested/nested array
* the string for NLA_REJECT
Remove the pointer and place appropriate type-safe items in the
union instead.
While at it, completely dissolve the pointer for the bitfield32
case and just put the value there directly.
