qcacld-3.0: Fix hw mode change issue in case of DBS

The driver stops the oppurtunitistic timer for DBS, when
the start AP requests come, which results in HW mode stuck
in DBS if the next vdev start request comes on the same MAC
This further results in NSS = 1 for the MAC, hence throughput
decreases.

Fix is to set hw mode to single MAC in case the STA/SAP comes up
in the band/channel
