SMP does ECB crypto on stack buffers.  This is complicated and
fragile, and it will not work if the stack is virtually allocated.

Switch to the crypto_cipher interface, which is simpler and safer.

Hi Dave-

It looks like we're delaying virtually mapped stacks to 4.9.  That
means that there's time for this to go in through net-next.  Could you
queue it up?

This needs to go via the bluetooth maintainer, who will surely pass
it properly my way.
