I don't see any issues with your pom. Just make sure that the path for you testng.xml is right
<suiteXmlfiles>src/test/resources/testng.xml</suiteXmlfiles>
One way to do this just place your testng.xml into your root folder where pom file is located and then change pom to:
<suiteXmlfiles>testng.xml</suiteXmlfiles>
Rerun and see!
