netlink: make validation_data const
The validation data is only used within the policy that
should usually already be const, and isn't changed in any
code that uses it. Therefore, make the validation_data
pointer const.
While at it, remove the duplicate variable in the bitfield
validation that I'd otherwise have to change to const.
