[PATCH 4/6] ib/mthca: change default node description processing

[ira.weiny-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org]

From: Ira Weiny <ira.weiny-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

Change the default node description string to IB_DEFAULT_ND_FORMAT
Use ib_build_node_desc to dynamically map this string when queried
