CVE-2023-52798: wifi: ath11k: fix dfs radar event locking
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix dfs radar event locking
The ath11k active pdevs are protected by RCU but the DFS radar event handling code calling ath11kmacgetarbypdevid() was not marked as a read-side critical section.
Mark the code in question as an RCU read-side critical section to avoid any potential use-after-free issues.
Compile tested only.
