qca-wifi: Access wlanstats context using CDP API

Browse Source 
Peer wlanstats context was accessed directly
without any protection, if peer was deleted
there was no way to know if PPDU cookie holds
correct wlanstats ctx

Hence to protect the peer wlanstats ctx access
it using CDP API using stats context protection
