[PATCH] crypto: catch base cipher self-test failures in fips mode

[Jarod Wilson]

I think this might have already been posted by Neil Horman, and
we already have it in the Red Hat Enterprise Linux 5.x kernels,
but in fips mode, we need to panic on the base cipher self-tests
failing as well as the later tests.
