wwan_create_dev() is expected to return either valid pointer or NULL,
In some cases it might return the error pointer. Prevent this by converting
it to NULL after wwan_dev_get_by_parent().

wwan_create_dev is called both from wwan_register_ops() and
wwan_create_port(), one using IS_ERR and the other using NULL testing,
they should be aligned as well.
