On digging into it, it turned out that the customer was probing an
aacraid device with an INQUIRY of 8 bytes.  The way aacraid works, it
was blindly trying to use aac_internal_transfer to copy the container
name to byte 16 of the inquiry data, resulting in a negative transfer
length.  It then copies over the whole of kernel memory before
dropping off the end.

Fix updated and corrected by Mark Salyzyn
