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.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
