Stefan Ginsberg b42aaf88bb - Fix recursive spinlock acquisition in Mm caused by locking inconsistency between ARM3 and the old ReactOS Mm. The old Mm calls certain routines to modify PFN entries (lock, unlock, reference, dereference, etc) and acquires/releases the PFN lock inside those functions (which is extremely inefficient as you can't, for example, have to acquire/release the PFN lock twice to reference and lock the same page), while ARM3 synchronizes differently and holds the lock while calling those routines, resulting in a recursive lock attempt on MP (which works on UP because spinlocks are just IRQL raise/lower there). Move out locking from MmAllocPage, MmReference/DereferencePage and MmLock/UnlockPage to the callers to be consistent with ARM3.

- Add missing PFN locking to MmFreePagesFromMdl and MiAllocatePoolPages.
- Get rid of MmLockPageUnsafe and MmReferencePageUnsafe. The "safe" routines just forwarded to the unsafe versions -- call them directly instead. Remove unused MmAcquirePageListLock/MmReleasePageListLock.
