io_uring/io_uring.c:432 io_prep_async_work() error: we previously
assumed 'req->file' could be null (see line 425).
Even though it's a false positive as there will not be REQ_F_ISREG set
without a file, let's add a simple check to make the kernel test robot
happy. We don't care about performance here, but assumingly it'll be
optimised out by the compiler.
