src: add nft_*_attr_{set|get}_data interface

This patch adds two functions that allows you to validate the size
of the attribute. This new functions provide a replacement for
nft_rule_attr_set and nft_rule_attr_get.

The data_len parameter was already passed to the {_set|_get} funcion
in expressions. For consistency, add nft_rule_expr_{set|get}_data
alias.
