debugfs: change parameter check in debugfs_remove() functions
The dentry parameter in debugfs_remove() and debugfs_remove_recursive() is checked being a NULL pointer. To make cleanup by callers easier this check is extended using the IS_ERR_OR_NULL macro instead because the debugfs_create_... functions can return a ERR_PTR() value.
