Kernel: Disable USB Mass Storage writing until I get it fixed

This prevented real hw from running for over 10-20 seconds. When first
disk sync happens after 10 secods, USB storage would enter faulty state
and not allow any io operations.

I have no idea what the problem is. If I don't send Reset command to the
USB device writing seems to work fine. I also don't think its part of
the Reset process either as reading works just fine.
