Eliminate sc_tx_cnt. Instead use an unsigned integer for sc_tx_prod and
sc_tx_cont and let them wrap around. Make sure we don't fill the last
descriptor on the ring such that we don't confuse a completely filled ring
with a completely empty one. Also make sure we don't post the same
descriptors twice.
