[S390] qdio: free indicator after reset is finished
The qdio device indicator is freed before the device is notified that the indicator is reset. This sequence contains a race when the freed indicator is used by a new device while the reset of the indicator is still pending. Do the reset operation before freeing the indicator to avoid that potential race. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
