mwifiex: add missing IEs related to TDLS operation

Browse Source 
In mwifiex,IEs such as supported channels, supported operating classes
20/40 BSS COexistence are missing and also extra QOS capabilities IE
is added during TDLS discovery response, TDLS setup request and
TDLS setupresponse.
This patch adds require IEs and also removes extra IE.
