crypto: hisilicon - still no need to check return value of debugfs_create functions
Just like in 4a97bfc796
("crypto: hisilicon - no need to check return
value of debugfs_create functions"), there still is no need to ever
check the return value. The function can work or not, but the code
logic should never do something different based on this.
