WiFi-HAL: Protect packet fate stats resources with mutex

Wifihal collects packet fate stats to a local buffer and the stats
will be copied to the buffers provided by framework in get() APIs.
Protect reads and writes to this buffer with a mutex to avoid
read from get() while write is going on in the event context
