netdevsim: delete unnecessary debugfs checking
In normal situations where the driver doesn't dereference
"nsim_node->ddir" or "nsim_node->rate_parent" itself then we are not
supposed to check the return from debugfs functions. In the case of
debugfs_create_dir() the check was wrong as well because it doesn't
return NULL, it returns error pointers.
