qdev-properties.h: Explicitly set the default value for arraylen properties
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.
