hwmon: (pmbus/max20730) delete some dead code 



The debugfs_create_dir() function never returns NULL.  Normal users are
not supposed to check the return value so the correct fix is just to
delete this check.

In the case where the debugfs_create_dir() fails, the function returns
NULL.  The other debugfs function check for NULL directory and handle
it.
