Fixed process init

Hi.

Take a look, please.

diff --git a/src/ngx_http_live_module.c b/src/ngx_http_live_module.c

     lmcf = ngx_http_cycle_get_module_main_conf(cycle, ngx_http_live_module);

+    if (ngx_process != NGX_PROCESS_WORKER) {

     if (lmcf == NULL || lmcf->nfd == 0) {
         return NGX_OK;
     }

Because the other non-worker processes like cache process is meaningless to involve socketpairs. And their value of ngx_worker is 0, thus they will occupy the same fd for reading.

for (n = 0; n < lmcf->nfd; n++) {
        if (n == ngx_worker) {
            fd = lmcf->read_fd[n];
            continue;
        }
...
