drm/amdgpu: Enable amdgpu_ttm_tt_get_user_pages in worker threads

Browse source

This commit allows amdgpu_ttm_tt_get_user_pages to work in a worker
thread rather than regular process context. This will be used when
KFD userptr BOs are restored after an MMU-notifier eviction.

v2: Manage task reference with get_task_struct/put_task_struct
