[PATCH 11/17] net/nfp: fix flow position index problem

[Chaoyong He]

From: Long Wu <long.wu at corigine.com>

The flow position acquire and free interfaces use different index,
and this will cause the flow free logic failed.

Fix this problem by using the same flow position index.

Fixes: 0b9079d24808 ("net/nfp: support flow API for CoreNIC firmware")
