Since we have a node that sets a mesh's auto smooth angle
(unfortunately, in retrospect), we generally can't assume at all
that value is the same as whatever input mesh. Similar asserts
were removed previously in 8216b759e9. While the attempt
at assertions to clarify assumptions is noble, this one doesn't
make sense anymore.
I found this while investigating T95479.
