Subject: [PATCH] rpc: socket: Don't repeatedly attempt to launch daemon

On every socket connect(2) attempt we were re-launching session
libvirtd, up to 100 times in 5 seconds.

This understandably caused some weird load races and intermittent
qemu:///session startup failures

(cherry picked from commit 2eb7a975756d05a5b54ab4acf60083beb6161ac6)
