crypto: iaa - Remove unnecessary debugfs_create_dir() error check in iaa_crypto_debug...

This patch removes the debugfs_create_dir() error checking in
iaa_crypto_debugfs_init(). 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.
