commit 7ac512aa82 upstream.
cachefiles_determine_cache_security() is expected to return with a
security override in place. However, if set_create_files_as() fails, we
fail to do this. In this case, we should just reinstate the security
override that was set by the caller.
Furthermore, if set_create_files_as() fails, we should dispose of the
new credentials we were in the process of creating.
