qcacld-3.0: Add OMN IE in assoc request if VHT op mode present

Browse Source 
If DUT connects to an AP in VHT mode with 40/80Mhz bandwidth in 5Ghz
band and then if user changes the country code(EC) where only 20Mhz
bandwidth present in 5ghz, then after association AP may ignore DUT's
support for only 20Mhz and keeps transmitting data in 40/80Mhz.
As DUT doesn't support these bandwidth, DUT doesn't ack the data
packets with higher received higher bandwidth. Thus DUT's RX throughout
degrades. This is an IOT issue where AP expects OMN IE with channel width
set to 20mhz . As DUT is not sending OMN IE low throughput issue is
observed

Hence host adds OMN ie in the association request only if the AP to
which DUT associates advertises OMN IE and DUT supports VHT.
