drm/panel-edp: fix i2c adapter leak on probe failure

The issue applies to Linux kernel systems using the drm/panel-edp driver where a devicetree redundantly sets the ddc-i2c-bus property to point to the auxiliary DDC bus.
2
When does the adapter reference leak occur?
The leak can occur when panel probe fails, including probe deferral, and when the driver is unbound under the affected devicetree configuration.
