Revert "net: Fix for initial link state in 2.6.28"

Browse Source 
This reverts commit 22604c8668.

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.
