[rdma-core PATCH] srp_daemon: Don't create async_ev_thread if only run once

[rdma-core PATCH] srp_daemon: Don't create async_ev_thread if only run once

[Honggang LI]

From: Honggang Li <honli-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

fd3005f0cd34 moves the signal handler setup from ibsrpdm path. So,
default signal handler will be used when the main pthread send signal
SIGINT to pthread async_ev_thread. ibsrpdm will exit with non-zero
exit code as default signal handler killed it. ibsrpdm should return
with exit code zero, if no error emerged.

We should not create async_ev_thread for ibsrpdm.

Fixes: fd3005f0cd34 ("srp_daemon: Move the setup of the wakeup_pipe after openlog")
