qcacld-3.0: Fix bss scoring params

Currently the driver calculates the nss score
based upon the max capability of the AP, and not the
hw_mde config which would be there after connection
for example, the driver calculates the score for a
2x2 11n AP, and 1x1 VHT (11ac) AP, it connects to the
11n AP in 1x1 mode, if a concurrent connection is
present, which affects throughput

Fix is to check whether the current AP channel results
in DBS or not, if yes then change the NSS to 1 instead of
2
