Trunk breakage

[Olaf Siejka]

I would like to ask everyone to hold a bit with commits, as trunk has now
regressed a bit. From revision 44885 (new pool code) we have crashes at
several places:

http://www.reactos.org/paste/index.php/6311/ servman
http://www.reactos.org/paste/index.php/6312/

The common part is ExAllocatePoolWithTag function.

Arm Ninja Team is asked for fixes.

Thanks in advance.
