[S390] dasd: fix endless loop in erp
If not enough memory is available to build a new erp request it ended up in an endless loop trying to build erp requests. Fixed the loop to proceed the next request instead. Signed-off-by: Stefan Haberland <stefan.haberland@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
