Subject: [PATCH] drbdadm,v9: do not segfault when re-configuring proxy with no
 path

This prevents a segfault when a resource has a connection with no path,
and "adjust" attempts to re-configure proxy.

This could occur as follows, when drbd-proxy-ctl is not on $PATH:
* Bring resource and connection up without proxy.
* Add proxy configuration to res file.
* "drbdadm adjust <res>" - this causes the existing path to be deleted,
  but no new path is created because drbd-proxy-ctl cannot be executed.
* "drbdadm adjust <res>" - segfault.
