qcacld-3.0: Add support to get last available vdev info

Browse Source 
FW sends vdev stats on vdev down, current host
implementation does not process this event as host is
only processing the stats events for which stats are
requested.
On vdev down FW sends the last available vdev stats and
based on that host updates it's RSSI on disconnect.
With CP stats infrastructure host is not processing
this event and is not updating rssi on disconnect.

To resolve this issue, add support to get last available
vdev stats from cp stats component with the help of a
callback registration.
