Jens Axboe 1da2f311ba io_uring: fix warnings on shadow variables 
There are a few of those:

io_uring/fdinfo.c:170:16: warning: declaration shadows a local variable [-Wshadow]
  170 |                 struct file *f = io_file_from_index(&ctx->file_table, i);
      |                              ^
io_uring/fdinfo.c:53:67: note: previous declaration is here
   53 | __cold void io_uring_show_fdinfo(struct seq_file *m, struct file *f)
      |                                                                   ^
io_uring/cancel.c:187:25: warning: declaration shadows a local variable [-Wshadow]
  187 |                 struct io_uring_task *tctx = node->task->io_uring;
      |                                       ^
io_uring/cancel.c:166:31: note: previous declaration is here
  166 |                              struct io_uring_task *tctx,
      |                                                    ^
io_uring/register.c:371:25: warning: declaration shadows a local variable [-Wshadow]
  371 |                 struct io_uring_task *tctx = node->task->io_uring;
      |                                       ^
io_uring/register.c:312:24: note: previous declaration is here
  312 |         struct io_uring_task *tctx = NULL;
      |                               ^

and a simple cleanup gets rid of them. For the fdinfo case, make a
distinction between the file being passed in (for the ring), and the
registered files we iterate. For the other two cases, just get rid of
shadowed variable, there's no reason to have a new one.
