USB: serial: fix potential use-after-free after failed probe

Browse source

Fix return value in probe error path, which could end up returning
success (0) on errors. This could in turn lead to use-after-free or
double free (e.g. in port_remove) when the port device is removed.

Fixes: c706ebdfc8 ("USB: usb-serial: call port_probe and port_remove
at the right times")
