rG24ae172a5035: ng_ubt(4): do not attach Realtek 87XX/88XX adaptors in bootloader mode.
Summary

Attempt to initialize FreeBSD bluetooth stack while such a device is in
bootloader mode locks the adapter hardly so it requires power on/off
cycle to restore.

This change blocks ng_ubt attachment unless operational firmware is
loaded thus preventing the lock up.
