Summary
tcp: Fix use-after-free of nreq in reqsk_timer_handler().
Details

In the Linux kernel, the following vulnerability has been resolved:

tcp: Fix use-after-free of nreq in reqsktimerhandler().

The cited commit replaced inetcskreqskqueuedropandput() with _inetcskreqskqueuedrop() and reqskput() in reqsktimerhandler().

Then, oreq should be passed to reqsk_put() instead of req; otherwise use-after-free of nreq could happen when reqsk is migrated but the retry attempt failed (e.g. due to timeout).

Let's pass oreq to reqsk_put().
