When a ring reset happens, amdgpu calls drm_dev_wedged_event() using struct amdgpu_task_info *ti as one of the arguments. After using *ti, a call to amdgpu_vm_put_task_info(ti) is required to correctly track its lifetime.However, it's called from a place that the ring reset path never reaches due to a goto after drm_dev_wedged_event() is called. Move amdgpu_vm_put_task_info() bellow the exit label to make sure that it's called regardless of the code path. amdgpu_vm_put_task_info() can only accept a valid address or NULL as argument, so initialise *ti to make sure we can call this function if *ti isn't used.
