qcacld-3.0: Don't set mon iface chan if iface is down during SSR

Telusuri Sumber 
After SSR host reinits and as a part of start all adapters host
starts monitor mode and sets the channel. To set the channel for
monitor mode, host send vdev start command to fw, at the same time
host checks for interfaces down during SSR. If the monitor mode is
down during SSR, host stops monitor mode adapter and sends vdev
delete command to fw. As a result, fw doesn't respond to vdev start
command and host receives only vdev delete response. Thus vdev
response timer timeout and host triggers self recovery.
Hence do not set monitor mode channel if monitor interfaces is down
during SSR.
