Log:
[NTOS/MM]
- Remove IMG_SCN_TYPE_NOLOAD support which was firstly removed by Alex, then reenabled by
Herve. Hopefully it works this time.
- Return proper image size after successfully mapping an image section (previously, 0 was
always returned). The change above is necessary for returning correct size.
