can: c_can: fix unbalanced runtime PM disable in error path

Runtime PM is enabled as one of the last steps of probe(), so all
earlier gotos to "exit_free_device" label were not correct and were
leading to unbalanced runtime PM disable depth.

Fixes: 6e2fe01 ("can: c_can: move runtime PM enable/disable to c_can_platform")
