In DEFINE_PROP_ARRAY, because we use a PropertyInfo (qdev_prop_arraylen)
which has a .set_default_value member we will set the field to a default
value. That default value will be zero, by the C rule that struct
initialization sets unmentioned members to zero if at least one member
is initialized. However it's clearer to state it explicitly.

If my eyeball of the sources is correct, this is the only case we
have of a Property struct that uses a PropertyInfo with a non-NULL
.set_default_value but which doesn't explicitly set .defval.u.
