s390/dasd: Remove unnecessary debugfs_create() return checks

Browse source

The DASD driver only uses the dentry pointers when removing debugfs
entries, and debugfs_remove() can safely handle both NULL and ERR_PTR.
There is therefore no need to check debugfs_create() return values.

This simplifies the debugfs setup code without changing functionality.
