qcacld-3.0: Add a check to validate BW for set ap cahn width

Browse source 
Currently driver does not validate BW before it invokes the kernel
api cfg80211_get_chandef_type. There is a WARN_ON in kernel
if above api is invoked with invalid BW.

To address above issue add a logic to validate the BW
before driver invokes the kernel api.
