[Cluster-devel] [PATCH 2/2] cman: fix printing of error if clustername is too long

[Fabio M. Di Nitto <fdinitto@redhat.com>]

Patch 03e9af7db105 did mask an error and was not propagating the
error string in the cman pipe, making it impossible to see the error
at startup when it is more important, since clustername cannot be changed
at runtime.

Resolves: rhbz#728230
