kernel - dm_target_crypt - use CRYPTO_F_BATCH

* Allow crypto requests to be dispatched to multiple crypto support
  threads instead of executing the operation synchronously.

* Greatly improves crypto performance on SMP boxes.  25MB/s -> 80MB/s on
  my quad.

* Currently the ivgen code gets in the way because it must be executed
  synchronously before the data crypto op can be initiated.  Further
  performance improvements are possible.
