Log:
- MC_NPPOOL is special-cased in the memory balancer core to always force the
allocation of a page, even in low-memory conditions (which in ReactOS, occur
early-on because, in a stroke of typical ReactOS genius, the balancer core is
called before the balancer initailizes its values and thresholds). Make
MC_SYSTEM special-cased as well, so we never fail to allocate page tables
early-on.
- This fixes booting on systems which required enough page tables such that the
balancer refused the allocation of new pages (around 64+16 pages for page
tables of 4KB each, ie. 320MB).
