qcacld-3.0: Use self cb mode check to change HT bandwidth

Currently, the driver uses the current capability to check
if it supports 40 MHz instead of self-cap, so once it
switches to 20 MHz it cannot switch back to 40 MHz again.

To fix check self capability to determine if the bandwidth
switch can be allowed in HT-only mode.
