From: Vasanthakumar Thiagarajan <quic_vthiagar@quicinc.com>

Currently, interface combination iterate callback gets notified for each
matching combination. To support multi-physical hardware interface
combination advertisements, the callback subscriber should additionally
receive the hardware index information to indicate which physical hardware
is chosen in the matching combination. Refactor the iterate callback by
introducing an argument for passing the hardware index. This hardware
index is valid for the multi-hardware advertisements and invalid (-1) for
the single hardware combination advertisement.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00188-QCAHKSWPL_SILICONZ-1
