Pavel Begunkov baf186c4d3 io_uring: index io_uring->xa by ctx not file ...

We don't use task file notes anymore, and no need left in indexing
task->io_uring->xa by file, and replace it with ctx. It's better
design-wise, especially since we keep a dangling file, and so have to
keep an eye on not dereferencing it.
