qcacmn: Add a flag to enable/disable per-packet sync of DP stats

Currently all Host collected DP statitics are synced to upper layers
on per-packet basis; This is causing significant CPU overhead.
Add a flag which can be controlled through iwpriv to enable/disable
updating of these statistics from DP to higher layers
