[PATCH v2 3/6] net/nfp: fix the set IPv6 flow action

[Chaoyong He]

The former logic of set IPv6 source/destination address flow action don't
consider the mask filed of control message passed to the firmware.
This caused the firmware skip the set action logic, and the offloaded
packets don't have the right IPv6 address as expected.

Fixes: 596ae2217214 ("net/nfp: support IPv6 source flow action")
Fixes: 51384f79b264 ("net/nfp: support IPv6 destination flow action")
