i965: Replace OUT_RELOC_FENCED with OUT_RELOC.

On Gen4+, OUT_RELOC_FENCED is equivalent to OUT_RELOC; libdrm silently
ignores the fenced flag:

        /* We never use HW fences for rendering on 965+ */
        if (bufmgr_gem->gen >= 4)
                need_fence = false;

Thanks to Eric for noticing this.
