qcacld-3.0: Add proper rates for MCS9 in host table

Currently the MCS9 rates are not populated correctly in the host stored
MCS tables. The current rates entered are (1560, 1733) which is incorrect.

Since MCS9 is not defined in the spec but rather an internal
implementation, rectify the rates by confirmation from firmware team.
The new rates entered are (1730, 1920)
