screenshot of the panic

I tried out the new QAT driver today with ZFS.  I'm using a Atom C2758 CPU with
14.0-CURRENT.  When I tried to create an encrypted file system, the kernel
immediately paniced.  Note that the same steps worked just fine without the qat
driver loaded.

# kldload qat
# mdctl -a -t malloc -s 1g
# zpool create crypttest /dev/md0
# zpool set feature at encryption=enabled crypttest
# zfs create -o encryption=aes-256-gcm -o keyformat=passphrase crypttest/t
