panfrost/decode: Futureproof texture dumping

One field was not dumped for some reason. It's observed to be 0, but
it's still good to have it available.

Also, extra fields might be snuck in the bitmaps array (it's
variable-lengthed at the end), and we want to guard against that
possibility, so we dump a little more.
