scsi: qla2xxx: Suppress gcc 7 fall-through warnings
Avoid that building with gcc 7 and W=1 triggers warnings similar to the following: drivers/scsi/qla2xxx/qla_isr.c:1189:27: warning: this statement may fall through [-Wimplicit-fallthrough=] Signed-off-by: Bart Van Assche <bart.vanassche@wdc.com> Cc: Himanshu Madhani <himanshu.madhani@cavium.com> Cc: Quinn Tran <quinn.tran@cavium.com> Cc: Hannes Reinecke <hare@suse.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
