dpaa_fq_setup() iterates through the queues allocated by dpaa_alloc_all_fqs()
and saved in &priv->dpaa_fq_list.

The allocation for FQ_TYPE_TX looks as follows:

	if (!dpaa_fq_alloc(dev, 0, dpaa_max_num_txqs(), list, FQ_TYPE_TX))
		goto fq_alloc_failed;

Thus, iterating again through FQ_TYPE_TX queues in dpaa_fq_setup() and
counting them will never yield an egress_cnt larger than the allocated
size, dpaa_max_num_txqs().

The comparison serves no purpose since it is always true; remove it.
