Now that the backlog manages the reschedule() logic correctly we can drop the partial fix to reschedule from recvmsg hook. Rescheduling on recvmsg hook was added to address a corner case where we still had data in the backlog state but had nothing to kick it and reschedule the backlog worker to run and finish copying data out of the state. This had a couple limitations, first it required user space to kick it introducing an unnecessary EBUSY and retry. Second it only handled the ingress case and egress redirects would still be hung. With the correct fix, pushing the reschedule logic down to where the enomem error occurs we can drop this fix.
