[patch 12/60] qdio: fix compile warning under 31 bit

[Martin Schwidefsky <schwidefsky@de.ibm.com>]

From: Jan Glauber <jang@linux.vnet.ibm.com>

The QEBSM instructions are only available for CONFIG_64BIT, they are not
used under 31 bit. Make compiler happy about the false positive:

drivers/s390/cio/qdio_main.c: In function ?qdio_inbound_q_done?:
drivers/s390/cio/qdio_main.c:532: warning: ?state? may be used uninitialized in this function
