qcacld-3.0: Fix VHT 160 rate report

1. Update pAddBssParams->ch_width to 160Mhz ch width value
based on VHT operation IE's ch width, channel segment 0
and channel segment 1 fields.

2. Report link rate information to OS for 160Mhz based on
rate flag TX_RATE_VHT160.

The change will fix the incorrect bandwdith reported by
IW commmand (iw wlan0 link) when STA is connected to AP
in VHT160 mode.
