[Intel-gfx] NULL ptr dereference in i915_gem_alloc_object()

Testing running out of file descriptors shows a NULL pointer dereference in i915_gem_alloc_object() because base.filp ends up being NULL. So the line mapping = file_inode(obj->base.filp)->i_mapping; will cause an oops. The call chain is SyS_ioctl -> do_vfs_ioctl -> drm_ioctl -> i
