qcacmn: Update vdev rate stats when user requests for vdev stats

Rate statistics are updated at both peer and vdev level in Tx HTT
and Rx monitor path.

As per peer optimization changes, macro DP_UPDATE_EXTD_STATS is used
for aggregation of extended stats and this macro is used for both peer
and vdev stats query.
With this approach, when user requests for vdev stats, then rate stats
for vdev are updated with the rate values of the last peer present in
peer list of vdev and this results in wrong output.

In order to fix this, add an API to update the rate stats for vdev
separately.
