[PATCH 09/11] Router: removed unused structure member proxy_buffers.

[Andrew Clayton]

proxy_buffers is declared as a structure member of nxt_socket_conf_t and
is set in nxt_router_conf_create(), however it is not used anywhere.

Removing it has the nice side effect of making the nxt_socket_conf_t
structure require one less cacheline (on x86-64 at least) as the summary
from pahole[0] shows

Before

    /* size: 200, cachelines: 4, members: 25 */
    /* sum members: 185, holes: 3, sum holes: 15 */

After

    /* size: 192, cachelines: 3, members: 24 */
    /* sum members: 177, holes: 3, sum holes: 15 */
