[DDRAW] Add missing dereference operators

[Andrey Turkin]

This patch adds several missing dereference operators because
COM_INTERFACE_CAST must operate on interface pointers and not pointers
to interface pointers. Fixes Inzomia Viewer crash (wouldn't show any
pictures but at least would run)

Patch is against 0.9.23

Changelog:
  Add missing dereference operators
