Subject: [PATCH] parser: fix parser so that cache creation failure doesn't
 cause load failure

This is a minimal patch so that it can be backported to 2.11 and 2.10
which reverts the abort on error failure when the cache can not be
created and write-cache is set.

This is meant as a temporary fix for
https://bugzilla.suse.com/show_bug.cgi?id=1069906
https://bugzilla.opensuse.org/show_bug.cgi?id=1074429

where the cache location is being mounted readonly and the cache
creation failure is causing policy to not be loaded. And the
thrown parser error to cause issues for openQA.

Note: A cache failure warning will be reported after the policy load.
