wlan: Increase number of buckets to categorize roamable APs

Roamable candidates found after scanning are categorized into buckets
based on their respective RSSI. Currently, width of each bucket is
defaulted to 30 and the number of buckets is set to 5. Due to this, all
roam candidates within -60 to -90 dBm fall into a single bucket. Roam
candidates from the same bucket are then sorted based on their
capabilities. Hence, it is possible that we might pick an AP with -89
dBm ahead of another candidate AP with -61 dBm.This problem is fixed by
increasing the number of buckets and reducing the width between the
buckets. This check-in brings in support for a width of 5 dBm
(configurable through ini parameter gRssiCatGap) and increases the
number of buckets to 15.
