qcacld-3.0: Populate and send correct max rate to the userspace

Browse source 
When the ini gReportMaxLinkSpeed is set, it indicates that the rates
provided to the userspace should give the maximum possible rate for the
given connected parameters. But currently in the driver, the max rate
that is being sent to the userspace is dependent on the NSS at which
the tx/rx is being done. The NSS is calculated by taking the union of
the value from assoc req and from the rate table using MCS index/rates
from firmware. The rates fluctuate as per the tx/rx by firmware which
subsequently affects the NSS in the host.

To keep the max rate independent of this changing NSS, decouple the NSS
calculation to contain the value from only the assoc req when reporting
max rate.
