Currently, we are only explicitly setting SOCK_NOSPACE on a write timeout for non-blocking sockets. Epoll() edge-trigger mode relies on SOCK_NOSPACE being set when -EAGAIN is returned to ensure that EPOLLOUT is raised. Expand the setting of SOCK_NOSPACE to non-blocking sockets as well that can use SO_SNDTIMEO to adjust their write timeout. This mirrors the behavior that Eric Dumazet introduced for tcp sockets.
