extcon: Use dev_of_node(dev) instead of dev->of_node 

JIRA: https://issues.redhat.com/browse/RHEL-37673

commit 9b4aea51cbcaefacaac655392f360bb3929ab63d
Author: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
Date: Wed, 22 Mar 2023 16:40:01 +0200

  The dev_of_node function should be preferred.
  In the result we may drop unneeded NULL check
  of the pointer to the device object.
