qcacld-3.0: Remove rate_set fields from struct sap_context

Change I3226438b908a96f1b1bd3c2968a0c20eef81a799 ("qcacld-3.0:
Populate correct supported rates from hostapd.conf file") removed
the logic which previously utilized the supp_rate_set and
extended_rate_set fields in struct sap_context. Since these fields
are now obsolete, remove them.
