Keith Busch b5875222de NVMe: IO ending fixes on surprise removal ... This patch fixes a lost request discovered during IO + hot removal. The driver's pci removal deletes gendisks prior to shutting down the controller to allow dirty data to sync. Dirty data can not be synced on a surprise removal, though, and would potentially block indefinitely. The driver previously had marked the queue as dying in this scenario to prevent new requests from attempting, however it will still block for requests that already entered the queue. This patch fixes this by quiescing IO first, then aborting the requeued requests before deleting disks.
