Log message:
more cleanup on close to avoid a use after free

In Linux, some driver specific cleanup is handled with the release
function pointer in struct file_operations.

For amdgpu, this was changed in Linux 6.16 from drm_release() to
amdgpu_drm_release().  Add a file_close function pointer to
struct drm_driver so we can call a function that does the same cleanup.
