Subject: [PATCH 1/2] wifi: ath10k: use = {} to initialize pm_qos_request instead of memset

Initialize the pm_qos_request structure using = {} instead of memset() in
ath10k_download_fw(). This ensures the structure is properly zeroed before
passing it to cpu_latency_qos_add_request(), and improves efficiency by
avoiding an explicit runtime memset.
