iwlwifi: mvm: don't use SAR Geo if basic SAR is not used

Browse source

commit 5d041c46cc upstream.

We can't use SAR Geo if basic SAR is not enabled, since the SAR Geo
tables define offsets in relation to the basic SAR table in use.

To fix this, make iwl_mvm_sar_init() return one in case WRDS is not
available, so we can skip reading WGDS entirely.
