hwmon: (pmbus/ucd9000) Drop unnecessary error check for debugfs_create_dir

Browse Source 
This patch removes the error checking for debugfs_create_dir
in ucd9000.c. This is because the debugfs_create_dir() does not
return NULL but an ERR_PTR after an error.
The DebugFS kernel API is developed in a way that the
caller can safely ignore the errors that occur during
the creation of DebugFS nodes.The debugfs Api handles
it gracefully. The check is unnecessary.
