Subject: [PATCH iproute2-next 5/9] dcb: app: modify
 dcb_app_parse_mapping_cb for dcb-rewr reuse

When parsing APP table entries, priority and protocol is assigned from
value and key, respectively. Rewrite requires it opposite.

Modify the existing dcb_app_parse_mapping_cb for dcb-rewr reuse, by
using the newly introduced dcbnl attribute in the dcb_app_table struct.
