Dave Jiang eb1fa4819d ntb: Fix calculation ntb_transport_tx_free_entry()
commit 5a7693e6bbf19b22fd6c1d2c4b7beb0a03969e2c upstream.

ntb_transport_tx_free_entry() never returns 0 with the current
calculation. If head == tail, then it would return qp->tx_max_entry.
Change compare to tail >= head and when they are equal, a 0 would be
returned.
