drm/amdgpu: change vm->task_info handling

This patch changes the handling and lifecycle of vm->task_info object. The major changes are:

  • vm->task_info is a dynamically allocated ptr now, and its uasge is reference counted.
  • introducing two new helper funcs for task_info lifecycle management
    • amdgpu_vm_get_task_info: reference counts up task_info before returning this info
    • amdgpu_vm_put_task_info: reference counts down task_info
  • last put to task_info() frees task_info from the vm.

This patch also does logistical changes required for existing usage of vm->task_info.

V2: Do not block all the prints when task_info not found (Felix)

V3: Fixed review comments from Felix

  • Fix wrong indentation
  • No debug message for -ENOMEM
  • Add NULL check for task_info
  • Do not duplicate the debug messages (ti vs no ti)
  • Get first reference of task_info in vm_init(), put last in vm_fini()

V4: Fixed review comments from Felix

  • fix double reference increment in create_task_info
  • change amdgpu_vm_get_task_info_pasid
