iwlwifi: mvm: don't send SAR GEO command for 3160 devices
SAR GEO offsets are not supported on 3160 devices. The code was refactored and caused us to start sending the command anyway, which causes a FW assertion failure. Fix that only considering this feature supported on FW API with major version is 17 if the device is not 3160. Additionally, fix the caller of iwl_mvm_sar_geo_init() so that it checks for the return value, which it was ignoring.
