rpcrt4: Fix NdrConformantStringUnmarshall to always increment the buffer during unmarshalling.

safe_copy_from_buffer has the side-effect of incrementing the buffer and this still needs to be done when we point the memory into the buffer. (Thanks to Maarten Lankhorst for finding the mistake and suggesting a fix.)
