Add ath11k driver callback for sta_set_4addr() to queue new workq set_4addr_wk only once based on new boolean, use_4addr_set. sta_set_4addr() will be called during 4-addr STA association cases applicable for both AP and STA modes. In ath11k_sta_set_4addr_wk(), AP mode: WMI_PEER_USE_4ADDR will be set for the corresponding associated 4-addr STA(s) STA mode: WMI_PEER_USE_4ADDR will be set for the AP to which the 4-addr STA got associated.
