Add missing return value checks to fix the following issues reported by the static analyzer:
- vah_add_file() call when adding render node path to the AppArmor profile (line 1029) was not checked, while there are examples with return code check throughout the code. - vah_add_file() call when adding default render node path (line 1037) had the same issue. - virDriverLoadModule() call when loading the storage driver (line 908) was not checked, while there are examples with return code check throughout the code.
