[NTOS:MM:PS] Little fixes for NTDLL loading (reactos#7707)

- [NTOS:PS] `STATUS_INVALID_IMAGE_PROTECT` returned by `MmCheckSystemImage` should be a fatal error too.
- [NTOS:PS] Fix object attributes for opening NTDLL.
- [NTOS:MM] Remove `MmCheckSystemImage` unused parameter.
- [NTOS:MM] Inline `MmVerifyImageIsOkForMpUse` in `MmCheckSystemImage`, reducing a call to `RtlImageNtHeader`.
