Regardless of that, it will not work. GRE tunnel is not necessary.
However, going back and recreating your point-to-point sub-interface as a
multipoint subinterface IS necessary.
Both will then show up as the correct type of ISIS interface so everything
matches and is happy.
But Brian is right as well, you will also need to map clns.
Don't forget to choose the DIS appropriately as well!

Ahmed,
Yes you still need the 'frame-relay map clns' command. This is used
for protocol resolution of IS-IS on the VC, and is independent of the
network type IS-IS is using.
