acpi, nfit: fix module unload vs workqueue shutdown race
The workqueue may still be running when the devres callbacks start firing to deallocate an acpi_nfit_desc instance. Stop and flush the workqueue before letting any other devres de-allocations proceed. Reported-by: Linda Knippers <linda.knippers@hpe.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
