[PATCH] infiniband-diags/ibqueryerrors.c: use common node_name

[Sasha Khapyorsky <sashak-smomgflXvOZWk0Htik3J/w@public.gmane.org>]

Get common node_name string using remap_node_name() and use it over
reporting functions - in this way simplify the code, avoid multiple
remap_node searches and fix minor memory leaks.
