qcacld-3.0: Don't fill the vdev response wait queue for set channel command

In monitor mode, wma_set_channel api is filling the
vdev response wait queue before sending the WMI_PDEV_SET_CHANNEL_CMDID
command to firmware and expecting it will be dequeued after response
from firmware but firmware doesn't send any response
to PDEV set channel command which is causing WMA timeout.
Don't fill the vdev request wait queue for WMI_PDEV_SET_CHANNEL_CMDID
 command as firmware doesn't send any response.
