[ofiwg] how to react to error log messages

I do get a info struct back, but things don't look right (e.g.,
src_addrlen=0, src_addr= or missing things (e.g., ep_attr).  I
also noticed that this is only happening on my mac.  Seems to work
just fine on a linux system.  FWIW, I don't have a problem on my mac
if I send in an empty hints structure.

Not sure if the actual problem is worth tracking down, but better
error handling might be useful generally.
