serial: vt8500: add missing braces
Due to missing braces on an if statement, in presence of a device_node a port was always assigned -1, regardless of any alias entries in the device tree. Conversely, if device_node was NULL, an unitialized port ended up being used. This patch adds the missing braces, fixing the issues.
