[PATCH AUTOSEL 4.19 25/59] iwlwifi: exclude GEO SAR support for 3168

From: Luca Coelho <luciano.coelho@intel.com>

[ Upstream commit 12e36d98d3e5acf5fc57774e0a15906d55f30cb9 ]

We currently support two NICs in FW version 29, namely 7265D and 3168.
Out of these, only 7265D supports GEO SAR, so adjust the function that
checks for it accordingly.
