qcacld-3.0: Enable TSO/SG feature by the FEATURE_TSO/dp_sg_support 

The hdd_set_netdev_flags enable the TSO feature regardless of the
FEATURE_TSO, which will cause the performance regression issue on
the non-tso supported chip.

Enable TSO feature based on the FEATURE_TSO, and enable the SG feature
separately by ini dp_sg_support for legacy chip to fix it.
