[S390] qdio: prevent compile warning under CONFIG_32BIT 



Prevent the following compiler warning if compiling a 31 bit kernel:

drivers/s390/cio/qdio_main.c: In function ‘get_outbound_buffer_frontier’:
drivers/s390/cio/qdio_main.c:646:16: warning: ‘state’ may be used uninitialized in this function
  CC      lib/radix-tree.o
  CC      drivers/s390/scsi/zfcp_cfdc.o
drivers/s390/cio/qdio_main.c: In function ‘qdio_inbound_q_moved’:
drivers/s390/cio/qdio_main.c:479:16: warning: ‘state’ may be used uninitialized in this function
drivers/s390/cio/qdio_main.c:479:16: note: ‘state’ was declared here
