Bugfix: There is an exception when crawling Yardstick results

If there is no pod.yaml, the results data looks like,
{"status": 2, "result": "[Errno 2] No such file or directory: u'/home/opnfv/userconfig/pre_config/pod.yaml'"}

It will get an exception when reading value from file,
File "/usr/local/lib/python2.7/dist-packages/dovetail/report.py", line 327, in crawl_from_file
criteria = data['result']['criteria']
TypeError: string indices must be integers
