Revert "udp: avoid calling sock_def_readable() if possible"
This reverts commit 612b1c0dec5bc7367f90fc508448b8d0d7c05414. On a
scenario with multiple threads blocking on a recvfrom(), we need to call
sock_def_readable() on every __udp_enqueue_schedule_skb() otherwise the
threads won't be woken up as __skb_wait_for_more_packets() is using
prepare_to_wait_exclusive().
