qcacld-3.0: Cleanup sta connection info at close adapter

Currently driver cleanup sta connection info at stop
adapter because of which if query for sta connection info
comes after adapter restart, in that case driver is not able
to return this info.
For example according to new design of Android-S, framework
issues stop adapter after every disconnetion to update mac
address dynamically, after that it starts adapter again, now
if driver gets request for connection info, it is not able to
provide the connection info as it is already cleaned up on stop
adapter.

To address above issue, cleanup sta connection info at close
adapter instead of stop adapter.
