In add_expect_hci_list() we iterate through the entries of the
expect_hci_list as long as there is an opcode, which means currently
this relies on overflowing the buffer to detect the end of the list.

This is not great and when running with address sanitizer, the
out-of-bounds read gets detected and mgmt-tester aborts. Fix it by
adding a trailing zero-entry to all those lists.
