Right now, if we hit an error retrieving the exit code in HCS process.ExitCode, we return that 0 and that error. Golang convention says that if an error is returned the other values should not be used, but the caller of ExitCode in libcontainerd has to fall through if an error is received. Rather than return a success exit code in that failure case, we should return -1 to indicate a generic failure.
