[BUG] Fix header order issue in device_operators.cuh

[codereport]

In the #5704, an issue was discovered with the order of the headers included in the file. The issue discussed in the following comment thread: #5704 (comment) It seems like it has to do with Jitify requiring <simt/type_traits> while other files just depend on <type_traits> but the conflict seems to occur from including fixed_point.hpp before utilities/traits.hpp. This issue is being set up so that the root of this conflict can be addressed and resolved at a later date. Below is a list of some of the files dependency hierarchies:

Hi there!

@codereport, I tried to reproduce this issue but it seems that the issue has been fixed somehow. Can you or somebody verify that, please?

Hi @ttnghia, thanks for pointing this out. Looks like somewere along the way the issue self resolved. I have set up #7401 to remove the comment and will take the bug label off this issue.
