qcacld-3.0: Move cp stats to scheduler thread from kworker thread

Currently, cp stats are received through kworker thread context.
This causes race conditions/out of sync issues if any common data
structures are handled in parallel in scheduler thread context.
There is no need to receive the cp stats on kworker thread as per
current design. So, move the cp stats event handling to scheduler
thread to avoid any race conditions.
