Some transports, such as RDMA, would like to set the Maximum Data Transfer Size (MDTS) according to device/port/ctrl characteristics. This will enable the transport to set the optimal MDTS according to controller needs and device capabilities. Add a new nvmet transport op that is called during ctrl identification. This will not effect transports that don't implement this option. The return value of the new op is according to the NVMe spec definition for MDTS.
