tg3: Revise 5719 internal FIFO overflow solution
Commit cf79003d598b1f82a4caa0564107283b4f560e14, entitled
"tg3: Fix 5719 internal FIFO overflow problem", proposed a way to solve
an internal FIFO overflow problem. We have since discovered a slightly
better way to solve the problem. This patch changes the code so that
the problem is contained closer to the problem source.
