qcacld-3.0: Abort connection for next AP if SAP stop/start is pending

In the case of STA/CLI + STA/CLI, if an STA/CLI is in connecting state
and a disconnect is received on any other STA/CLI, the disconnect can
timeout waiting for the connection on the first STA/CLI to get completed.
This is because the connection is a blocking serialization command and
it can try multiple candidates and thus can take up to 30+ sec to
complete.

Same way if an SAP/GO has a start/stop command or peer disconnect in
pending queue, the delay is processing it can cause timeouts and other
issues.

So abort the next connection attempt if any of the vdev is waiting
for vdev operation to avoid timeouts.
