qcacld-3.0: Fix default value of beamformee STS Capability for SAP

Browse Source 
A VHT beamformee shall indicate the maximum number of space-time
streams it can receive in a VHT NDP in the Beamformee STS
Capability subfield of the VHT Capabilities Information field of
the VHT Capabilities element. The SAP is advertising STS value
as 8 in both 2G and 5G band. This may cause IOT issues.

Fix the default value of beamformee STS capability value as
default value 3 for SAP.
