Increase max management version to accommodate OPA

Allocation of MAD base and class version numbers is owned by the IBTA.
It doesn't seem appropriate to arbitrarily claim code points without proper
approval.

OPA is its own architecture space.  While this space uses some of the same values as 
IB we are not claiming any IBTA values.  

You *are* claiming IBTA values. When the IBTA chooses to use those
values, then there will be a conflict.

This is similar to how IB GIDs and IPv6 addresses look the same but are in separate addressing domains.
