s390/zcore: no need to check return value of debugfs_create functions 



When calling debugfs functions, there 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.

See commit 7dd541a3 ("s390: no need to check return value of debugfs_create functions").
