[S390] qdio: reset outbound SBAL error states
Don't leave outbound SBALs in error state after a target full condition. Reset the state to not initialized to make the error handling consistent across all types of errors. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
