[S390] dasd: fix use after free in dbf
Writing to /proc/dasd/statistics while the debug level of the generic dasd debug entry is set to DBF_DEBUG will lead to an use after free when accessing the debug entry later. Since for the format string "%s" in the s390 dbf only a pointer to the string is stored in the debug feature and the buffer used here is freed afterwards. To fix this just remove the debug message.
