ntb: Fix calculation ntb_transport_tx_free_entry()
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.
Fixes: e74bfeedad08 ("NTB: Add flow control to the ntb_netdev")
