drm/amdkfd: Init mqd managers in device queue manager init 

Previously mqd managers was initialized on demand. As there
are only a few type of mqd managers, the on demand initialization
doesn't save too much memory. Initialize them on device
queue initialization instead and delete the get_mqd_manager
interface. This makes codes more organized for future changes.
