qcacld-3.0: Handle NAN+STA reconnect concurrency 

Currently, STA reconnect (e.g. reconnect to same BSSID) is handled
as STA+STA as part of NAN concurrency checks. This results in NAN
disable when reconnect is issued.
Check if the current incoming connection is on same vdev as
previous sta connection instance and disable NAN only if it's
different.
Handle NAN+SAP reenable in similar way.
Also, remove the redundant usage of NDI cleanup API
ucfg_nan_check_and_disable_unsupported_ndi in
if_mgr_connect_start.
