qcacld-3.0: Do not enable STA roaming if any NDI connection is active

Host disables STA roaming if any active NDI connection is present using
"sta_disable_roam" ini.

If NDI connection comes first and then STA connects to AP, then host
enables STA roaming in the association completion of STA. If STA
disconnects, roam scan is triggered which adds glitch in NDI connection.

Hence enable STA roaming if there are no active NDI connections.
