wifi: ath11k: 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
ath11k_debugfs_fw_stats_process() we wait 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)
finally the requestor would be blocked until wait 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
wait directly; if not, follow the old way.
