State in global ttm structures was not properly reset on cleanup. In the scenario where multiple drm drivers are loaded and the first one fails to initialize, there is an attempt to reset the global state in the ttm structures. However, there were some attributes which were not properly reset during this process. This resulted in a crash and false positive kobj initialization warnings during subsequent initialization of these global structures.
Fix the crash and false positive kobj initialization warnings. --- Changes in v2: State in global ttm structures is reset by means of zeroing memory in global structure initialization functions rather than checking reference counters in their corresponding release functions.
