wifi: ath12k: Assert base_lock is held before allocating REO update element 



Add a lockdep assertion to verify that ab->base_lock is held prior to
allocating a REO update element in ath12k_dp_prepare_reo_update_elem().
This helps detect potential concurrency issues during development and
improves code robustness.
Compiled tested only.
