qcacmn: Modify maximum BW only conditionally

Browse source 
The maximum BW for edge channels may fall outside the low limit or
high limit of channel range for a given pdev. But reduce the maximum
BW only if it is less than or equal to 20 MHz. Higher bandwidths are
realized using channel bonding and the channel itself may not be center
channel.
