commit 40264438e5320d4bf2cde5d8c1c2ddc4637d3042
Author: Nicolas Morey-Chaisemartin <nmoreychaisemartin@suse.com>

ucm, mcm: fix backlog parameter for socket
Using listen(, 0) forces a synchronization barrier between connect and accept
if net.ipv4.tcp_syncookies. As this is done by a single thread, it causes connect
to timeout with a similar message:
open_hca: failed to init cr pipe - Connection timed out
Replace with listen(, 1) so the kernel can accept the connection itself and remove
the synchronisation point.
