Subject: [PATCH v5] pktcdvd:Remove unnecessary debugfs_create_dir() error check in pkt_debugfs_dev_new()

This patch removes the debugfs_create_dir() error checking in
pkt_debugfs_dev_new(). Because the debugfs_create_dir() is developed
in a way that the caller can safely handle the errors that
occur during the creation of DebugFS nodes.
