io_uring: use original request task for inflight tracking
commit 386e4fb6962b9f248a80f8870aea0870ca603e89 upstream.
In prior kernels, we did file assignment always at prep time. This meant
that req->task == current. But after deferring that assignment and then
pushing the inflight tracking back in, we've got the inflight tracking
using current when it should in fact now be using req->task.
Fixup that error introduced by adding the inflight tracking back after
file assignments got modifed.
Fixes: 9cae36a094e7 ("io_uring: reinstate the inflight tracking")
