wifi: ath11k: fix memory leak in WMI firmware stats

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.
