Kiran Kumar Lokere a92660a00e Work around Supported Operating Classes element issues for 6 GHz 
IEEE Std 802.11 specifies that the Operating Classes field terminates
immediately before the OneHundredAndThirty Delimiter (i.e., an octet
with value 130). Move the operating class value 130 last in the global
op_class array so that it gets added as the last entry into the
Supported Operating Clases element and the 6 GHz operating class is
parsed in that element by implementation that stop at the assumed
OneHundredAndThirty Delimiter.
