Revert "net: Fix for initial link state in 2.6.28"
This reverts commit 22604c866889c4b2e12b73cbf1683bda1b72a313.
We can't fix this issue in this way, because we now can try
to take the dev_base_lock rwlock as a writer in software interrupt
context and that is not allowed without major surgery elsewhere.
This initial link state problem needs to be solved in some other
way.
