This patch remove the error checking in pktcdvd.c.
The DebugFS kernel API is developed in
a way that the caller can safely ignore the errors that
occur during the creation of DebugFS nodes.
The comment above debugfs_create_dir includes the following text.
* NOTE: it's expected that most callers should _ignore_ the errors returned
* by this function. Other debugfs functions handle the fact that the "dentry"
* passed to them could be an error and they don't crash in that case.
* Drivers should generally work fine even if debugfs fails to init anyway.
