uwb: i1480-dfu: fix NULL-deref at probe

Browse source

commit 4ce362711d 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 cmd and wait_init_done
callbacks which are called during probe.
