qcacld-3.0: Report HT TX STBC capability to kernel
Propagate from qcacld-2.0 to qcacld-3.0
Currently the driver does not report HT TX STBC capability
to the kernel. This prevents hostapd from starting if it
has been configured with HT TX STBC capability. To prevent
this issue correctly report the HT TX STBC capability to the
kernel.
