The radio for which the survey info needs to be collected
depends on the channel idx which could be based on the band.
Use the idx to identify the appropriate sband since multiple
bands could be combined for single wiphy case.

Also use the channel idx and sband to identify the corresponding
radio on which the survey results needs to be populated.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
