[NTOSKRNL]

Improve the oplocks stubs:
- Always return success when FsRtlCheckOplock() is called: we deny oplock creation at FsRtlOplockFsctrl(), so the oplocks can only be fine.
- Always return TRUE when FsRtlOplockIsFastIoPossible() is called: we deny oplock creation at FsRtlOplockFsctrl(), so no oplock can prevent fastio from happening.

This enables (for real :-)) write support in extX FSD. Not 100% perfect though, as it hits an assert in MCB (but that's yet another story).

Full implementation to come later on.
