 * The FW sends the HTT EXT STATS as a stream of T2H messages. Each T2H message
 * contains sub messages which are identified by a TLV header.
 * In this function we will process the stream of T2H messages and read all the
 * TLV contained in the message.
 *
 * THe following cases have been taken care of
 * Case 1: When the tlv_remain_length <= msg_remain_length of HTT MSG buffer
 *		In this case the buffer will contain multiple tlvs.
 * Case 2: When the tlv_remain_length > msg_remain_length of HTT MSG buffer.
 *		Only one tlv will be contained in the HTT message and this tag
 *		will extend onto the next buffer.
 * Case 3: When the buffer is the continuation of the previous message
 * Case 4: tlv length is 0. which will indicate the end of message
