ioat: wait for self-test completion
commit
532d3b1f86f41834a25373e3ded981d68e4ce17f upstream.
As part of the ioat_dma self-test it performs a printk from a completion
callback. Depending on the system console configuration this output can
take longer than a millisecond causing the self-test to fail. Introduce a
completion with a generous timeout to mitigate this failure.
