iwlwifi: provide gso_type to GSO packets

Browse Source 
commit 81a86e1bd8 upstream.

net/core/tso.c got recent support for USO, and this broke iwlfifi
because the driver implemented a limited form of GSO.

Providing ->gso_type allows for skb_is_gso_tcp() to provide
a correct result.

Fixes: 3d5b459ba0 ("net: tso: add UDP segmentation support")
