So I just realized that the BITE tests were only done for mgmtops.c and
not hciops.c. One critical difference is that conn->key_type will not be
set (or actually set to 0xff) for connections which happen after the
initial pairing has occurred. We're right now testing a one-line patch
which might fix the issue. Luiz will send it soon if it turns out to
work fine.
