Currently, rss_size = num_tqps / tc_num. If tc_num is 1, then num_tqps
equals rss_size. However, if the tc_num is greater than 1, then rss_size
will be less than num_tqps, causing the tqp_index check for subsequent TCs
using rss_size to always fail.
This patch uses the num_tqps to check whether tqp_index is out of range,
instead of rss_size.
