Fix bug #7733 - Invalid client DOS attributes on create can cause incorrect unix mode_t to be generated.
It turns out a client can send an NTCreateX call for a new file, but specify FILE_ATTRIBUTE_DIRECTORY in the attribute list. Windows silently strips this, but we don't - causing the unix_mode() function to go through the "mode bits for new directory" codepath, instead of the "mode bits for new file" codepath. Jeremy.
