tg3: Revert PCIe tx glitch fix
This patch reverts commit 52cdf8526fe24f11d300b75458ddee017f3f4c88,
entitled "tg3: Prevent a PCIe tx glitch". The problem does not have
any visible side-effects and happens too early for the driver to do
anything about it. The proper place for this code is within the
device's bootcode.
