[openib-general] [PATCH] osmtest: fix node_desc.description as string usages

[Sasha Khapyorsky]

node_desc.description buffer is received from the network and should
not be NULL-terminated. In such cases using it as regular string in
functions like printf() leads to segmentation faults. This patch fixes
such usages.
