[S390] qdio: fix broken pointer in case of CONFIG_DEBUG_FS is disabled
If CONFIG_DEBUG_FS is disabled debugfs_create_file returns -ENODEV instead
of zero. Since the return value is stored and used at shutdown to remove
existing entries an OOPS may be triggered.
Add a check of the debugfs_create_file return value and in case of an error
set the entry to NULL so it will be ignored at shutdown.
