io_uring: don't re-setup vecs/iter in io_resumit_prep() is already there

If we already have mapped the necessary data for retry, then don't set
it up again. It's a pointless operation, and we leak the iovec if it's
a large (non-stack) vec.

Fixes: b63534c41e20 ("io_uring: re-issue block requests that failed because of resources")
