Wlan: Enable WMM-QoS for HT capable TDLS peers

During TDLS session establishment, assume the peer is HT
capable STA. If WMM-QoS is enabled in the DUT, but the TDLS
peer does not have WMM/WME IE in TDLS Setup Request/Response
and has QoS Capability element, then the DUT does not
transmit data with QoS. Thus, the throughput gets decreased.

Fix is to enable QoS for the STA for TDLS session if the peer
is HT/VHT capable or WMM/WME IE is present.
