If corosync goes down/is shut down cman will return 0 from cman_dispatch
and close the socket. However, if a cman write operation is issued
before this happens then SIGPIPE can result from the writev() call to an
open, but disconnected, FD.
This patch changes writev() to sendmg() so it can pass MSG_NOSIGNAL to
the system call and prevent SIGPIPEs from occurring.
