src: fix bogus assertion for unset attributes

If you try to obtain an unset attribute, you hit an assertion error
that should not happen. Fix this by checking if the attribute is
unset, otherwise skip the assertion checking.

Now that we have that nft_assert takes the data parameter, we can also
validate if someone is using the setter passing NULL, which is illegal.
So let's add an assertion for that as well.
