[libvirt] [PATCH v2 22/42] test: add default: case to all switch statements

Even if the compiler has validated that all enum constants have case statements in a switch, it is not safe to omit a default: case statement. When assigning a value to a variable / struct field that is defined with an enum type, nothing prevents an invalid value being assigned. So defensive code must assume existance of invalid values and thus all switches should have a default: case. Signed-off-by: Daniel P.
