Subject: [PATCH] osm_prtn_config.c: Some changes to
 osm_prtn_config_parse_file

in terms of deciding when partition file is valid or not and
hence when to fallback to default partition configuration.

Improvements to commit 5a97c782a4b4f968c2d964c371decec5083f8499
    Try default partition config if parsing partitions.conf fails

Specific changes are:
break out of global while on a parsing failure
change is_parse_success to int from boolean and reverse logic setting this
also, detect whether there is at least one valid partition parsed
