qcacmn: Change default DSCP-TID mapping table to use all TIDs

Browse source 
Change default DSCP-TID mapping table so that all possible TID
values can be used in transmit datapath.
Also propagate a fix from legacy Tx classification code required
to compute the offset of L3 header pointer correctly
