File reference cycles have caused lots of problems for io_uring

disallow sending io_uring files via sockets via SCM_RIGHT, so there
are no possible cycles invloving registered files and thus rendering
SCM accounting on the io_uring side unnecessary.

Here is the summary with links:

It has already been taken by Jens into the io_uring tree, and a pr
with it was merged by Linus. I think it should be dropped from
the net tree?
