The free_sge_txq_old() function has an unnecessary txq check of 0.
This check is not necessary, since the txq pointer is initialized by the
uldtxq[i] address from the operation &txq_info->uldtxq[i], which ensures
that txq is not equal to 0.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: ab677ff4ad15 ("cxgb4: Allocate Tx queues dynamically")
