[FIX] Smarty: fixed plugin_edit_row being the name for all plugin parameters

The name variable inside a function is returning the function name overriding the name parameter passed to that function.

{CODE(plugin_edit_row="Test" plugin_edit_row="1" plugin_edit_row="red" plugin_edit_row="default")}Hello{CODE}

This is an example of code generation when using plugin help.
