Johan Hovold 2e7486a05b uwb: hwa-rc: fix NULL-deref at probe ...

commit daf229b159 upstream.

Make sure to check the number of endpoints to avoid dereferencing a
NULL-pointer should a malicious device lack endpoints.

Note that the dereference happens in the start callback which is called
during probe.
