Dan Williams e471486c13 acpi, nfit: fix acpi_nfit_flush_probe() crash ... We queue an on-stack work item to 'nfit_wq' and wait for it to complete as part of a 'flush_probe' request. However, if the user cancels the wait we need to make sure the item is flushed from the queue otherwise we are leaving an out-of-scope stack address on the work list.
