Benjamin Otte 9581d060d2 dmabuf: Fix disjoint detection 
According to the Mesa developers, the correct way to determine
disjointness is to check the actual inode of the fd because dup()ing can
cause these duplications to happen when planes are carelessly copied or
when planes are sent over dbus or other unix sockets.
