[openib-general] [PATCH] osm: OpenSM exits on PathRecord query with zero LID

[Eitan Zahavi]

Hi Hal,

This is another catch from the nightly simulator based regression.
Simple: if OpenSM gets a PathRecord that eventually maps into a port 
with zero LID (either SRC or DST)
if just asserts (in debug mode) on getting the LFT.

The following patch catches this error.
