ima/policy: fix parsing of fsuuid
commit36447456e1
upstream. The switch to uuid_t invereted the logic of verfication that &entry->fsuuid is zero during parsing of "fsuuid=" rule. Instead of making sure the &entry->fsuuid field is not attempted to be overwritten, we bail out for perfectly correct rule. Fixes:787d8c530a
