MBO: Fix the allowed range of mbo_assoc_disallow values
This parameter was added with the commit message indicating the valid
reason code values to be 1-5, but with the implementation allowed only
1. There are five defined reason code values for the Association
Disallowed attribute, so extend the allowed range to cover all those
values.
