RFR: JDK-8227124: "could not open pipe" error does not report error details

Hi Alex,

I think the calls to GetLastError() should be in the else clauses, just 
before or as part of the log_error() statements. Otherwise you are 
making the GetLastError() calls even when there is no error.

thanks,

Chris
