Christopher Kohlhoff d7525504d0 Fix initialization of sqe->user_data for reuse by io_uring_service. ...

The value of user_data in a submission queue entry is only initialized
with with the ring itself, remaining unchanged after use and even
through calls to io_uring_get_sqe(3). Many submission paths apply
io_uring_sqe_set_data(3) but the remainder are submitted with stale
values that can apply completion operations on the wrong queues with the
wrong results, causing obscure bugs.
