In SAP on non DFS channel, there are double votes for PCIe
link down and later if there is PCIe link up, this counter
sends D3 WoW case instead of D0 WoW case to firmware.
To fix this, In vdev restart case, if SAP is on non DFS
channel and previously it was on DFS channel then vote
for PCIe link down and if SAP is on DFS channel and
previously it was on non DFS channel then vote for PCIe
link up. Also, the PCIe link down should be needed if
vdev stop response is for DFS channel.
