wifi: ath12k: convert struct ath12k_sta::update_wk to use struct wiphy_work
For preparation to switch ath12k to use wiphy_lock() we can convert ath12k_sta_rc_update_wk() to use wiphy_work_queue() for consistency. To avoid any deadlocks do the struct ath12k_sta::update_wk conversion before switching to using wiphy_lock() throughout the driver.
