qom: Clean up object_property_get_enum()'s error value
object_property_get_enum() is the only object_property_FOO() that is
documented to return an undefined value on error. It does no such
thing, actually: it returns 0 on some errors, and -1 on others.
Needlessly complicated. Always return -1 on error, and adjust the
contract.
