[PATCH libnftnl] expr: use NFTA_* netlink attributes to build fields, not NFTNL_EXPR_*

[PATCH libnftnl] expr: use NFTA_* netlink attributes to build fields, not NFTNL_EXPR_*

[Pablo Neira Ayuso]

Coincidentally NFTNL_EXPR_BASE starts at 1 which comes right after
NFTA_*_UNSPEC which is zero. And NFTNL_EXPR_ attribute values were
mapping to NFTA_* attributes.

Use NFTA_* for netlink attribute types instead.
