qcacld-3.0: Enable wide band scan for 2 link also

Currently, when user connect STA with 2 link AP and sends
"MEASURE_ML_CHANNEL_CONDITION" command to driver, the driver report
error. This is due to driver tries to fetch the link info for
3 link but only 2 link info is available. Hence, it gets invalid
link id for third link.

To fix this, add check for number of links and extract the data for
available links only.
