src: fix nft_*_unset function attribute that don't release data

In (dde2039 src: add nft_*_unset functions), I mangled Arturo's
patch to add a default case, but he was intentionally not adding
it to unset attributes that require no memory releases.

I prefered to add the attributes explicitly in the switch rather
on failing back on the default action.
