[PATCH] net/nfp: fix the incorrect vni of VXLAN encap action

[Chaoyong He]

The helper function which send the tunnel configuration to
firmware requires the vni with CPU endian.
The original VXLAN encap logic wrongly invoke it with the
big-endian value.

Fixes: 724662b4ce5b ("net/nfp: support IPv4 VXLAN encap flow action")
Fixes: c3b7254093c2 ("net/nfp: support IPv6 VXLAN encap flow action")
