IB/mad: Support alternate Base Versions when creating MADs
In preparation to support the new OPA MAD Base version, add a base version
parameter to ib_create_send_mad and set it to IB_MGMT_BASE_VERSION for current
users.
Definition of the new base version and it's processing will occur in later
patches.
