qcacld-3.0: Correct the actual rate flags being sent to framework

Presently, in VHT case also, the HT MCS rate flag is being set when the
SGI is enabled. This is causing the kernel to misinterpret the rates.
Instead of getting the VHT rates, the kernel is enabling the HT rates.
This issue is not present in kernel 4.9 as the preference was given to
VHT rates. For kernel 4.14, the preference is given to HT rates thus
highlighting the problem.

To solve this issue, do not set the RATE_INFO_FLAGS_MCS for SGI enabled.
