[PATCH] usb: typec: silence a static checker warning

Smatch complains about a potential missing error code:

    drivers/usb/typec/port-mapper.c:168 typec_link_port()
    warn: missing error code 'ret'

This is a false positive and returning zero is intentional.  Let's
re-arrange the code to silence the warning and make the intent more
clear.
