qcacld-3.0: Don't set operating channel before ROC gets finished

Vendor cmd(QCA_NL80211_VENDOR_SUBCMD_SET_PROBABLE_OPER_CHANNEL) in supplicant
has been designed to notify the driver about operating channel right after go
negotiation is completed, so that driver can get going with HW mode
change little ahead of time before the change iface/add iface req comes
down from supplicant for the CLI role. But it looks like the cmd is
coming even before RoC cancellation is done for the completed
negotiation. So, this delays the HW mode change req in FW as FW thinks
the scan (on going RoC) is not complete yet. As a result it waits for the RoC to
finish before entertaining the HW mode change req.

To fix this situation, don't set probable operating channel till RoC
gets finished.
