qcacld-3.0: Add vdev valid check for wmi vdev level commands

Check if vdev is active for the following roam related vdev
commands before sending it to wmi:
1. WMI_ROAM_SCAN_MODE
2. WMI_ROAM_SCAN_PERIOD
3. WMI_ROAM_SCAN_RSSI_CHANGE_THRESHOLD
4. WMI_ROAM_AP_PROFILE
5. WMI_ROAM_CHAN_LIST
6. WMI_ROAM_SCAN_CMD
7. WMI_ROAM_SYNCH_COMPLETE

This will avoid the race condition where the vdev is deleted
and the vdev related commands for the deleted vdev are sent
to firmware before wmi_stop_inprogress is set at wmi.
