qcacld-3.0: Do not send UAPSD enable command to FW

Browse source 
Currently, UAPSD enable command is sent to FW if
INI UapsdMask is set for any access category.
But, when twt is enabled then UAPSD auto trig
 commands should not be sent to FW. If both twt
and UAPSD is enabled in FW then it can lead
to data stalls.

Send UAPSD enable command to FW if twt is not supported.
