wifi: ath12k: don't wait when there is no vdev started

For WMI_REQUEST_VDEV_STAT request, firmware might split response into
multiple events dut to buffer limit, hence currently in
ath12k_wmi_fw_stats_process() host waits until all events received. In
case there is no vdev started, this results in that below condition
would never get satisfied

	((++ar->fw_stats.num_vdev_recvd) == total_vdevs_started)

consequently the requestor would be blocked until time out.

The same applies to WMI_REQUEST_BCN_STAT request as well due to:

	((++ar->fw_stats.num_bcn_recvd) == ar->num_started_vdevs)

Change to check the number of started vdev first: if it is zero, finish
directly; if not, follow the old way.
