Yifei Gao 90af7fde08 memstick: ms_block: destroy io_queue workqueue on removal ...

msb_init_disk() creates the per-card ordered workqueue msb->io_queue with
alloc_ordered_workqueue(). It is torn down with destroy_workqueue() only
on the init error path; msb_remove() never destroys it. msb_stop() merely
flushes the queue, and neither msb_data_clear() nor put_disk() free it. As
a result every card insert/remove cycle leaks the workqueue and its
kworker, exhausting kernel memory over repeated cycles.

Destroy the workqueue in msb_remove() after the disk has been removed and
the queue drained.
