async_tx: raid6 recovery self test
Port drivers/md/raid6test/test.c to use the async raid6 recovery routines. This is meant as a unit test for raid6 acceleration drivers. In addition to the 16-drive test case this implements tests for the 4-disk and 5-disk special cases (dma devices can not generically handle less than 2 sources), and adds a test for the D+Q case.

+ This is a one-shot self test that permutes through the

+ N-disk array. Recovery is performed with the asynchronous
+ raid6 recovery routines, and will optionally use an offload
+ engine if one is available.
