qcacmn: Extract tid from REO descriptor and save to skb cb

Browse Source 
earlier we were extracting the tid from the rx tlvs, this
was in the last cache line of the 384 byte tlv. we are
extracting various fields from REO descriptor, now we are
also getting tid from the descriptor to avoid accessing
the last cache line of rx TLV there by avoiding one
cache miss per packet.
