What it is

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath11k: fix memory leak in WMI firmware stats

Memory allocated for firmware pdev, vdev and beacon statistics

are not released during rmmod.

Fix it by calling ath11k_fw_stats_free() function before hardware

unregister.

While at it, avoid calling ath11k_fw_stats_free() while processing

the firmware stats received in the WMI event because the local list

is getting spliced and reinitialised and hence there are no elements

in the list after splicing.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1
