PCI/DOE: Deduplicate mailbox flushing
When a DOE mailbox is torn down, its workqueue is flushed once in
pci_doe_flush_mb() through a call to flush_workqueue() and subsequently
flushed once more in pci_doe_destroy_workqueue() through a call to
destroy_workqueue().
Deduplicate by dropping flush_workqueue() from pci_doe_flush_mb().
Rename pci_doe_flush_mb() to pci_doe_cancel_tasks() to more aptly
describe what it now does.
