mtd: blktrans: Hotplug fixes
* Add locking where it was missing.
* Don't do a get_mtd_device in blktrans_open because it would lead to a
deadlock; instead do that in add_mtd_blktrans_dev.
* Only free the mtd_blktrans_dev structure when the last user exits.
* Flush request queue on device removal.
* Track users, and call tr->release in del_mtd_blktrans_dev
Due to that ->open and release aren't called more that once.
Now it is safe to call del_mtd_blktrans_dev while the device is still in use.
