[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.
