wifi: iwlwifi: mvm: avoid link lookup in statistics
We already iterate the link bss_conf/link_info and have the pointer, or know that deflink/bss_conf is used, so avoid an extra lookup and just pass the pointer. This may also avoid a crash when this is processed during restart, where the FW to link conf array (link_id_to_link_conf) may be NULLed out.
