io_uring: don't setup async context for read/write fixed

We don't need it, and if we have it, then the retry handler will attempt
to copy the non-existent iovec with the inline iovec, with a segment
count that doesn't make sense.

Fixes: f67676d160c6 ("io_uring: ensure async punted read/write requests copy iovec")
