qcacld-3.0: Fix wrong bandwidth upgrade for STA

Browse Source 
STA connected to an 2.4 GHz BSS fails to get IP
due to VDEV restart triggered by bandwidth upgrade.
Wrong bandwidth upgrade happens upon the reception
of the first beacon after connection.

Beacon opmode change logic considers supported channel
width cap in the HT capability IE to retrieve the
bandwidth of 2.4 GHz BSS. However, the AP can support
both 20 & 40 MHz, so using this capability will lead to
wrong bandwidth upgrade.

Use the recommended channel width set from HT Info IE
to retrieve the proper bandwidth.
