From: Eric Biggers <ebiggers@xxxxxxxxxx>
When alg_test() is called from tcrypt.ko rather than from the algorithm
registration code, "driver" is actually the algorithm name, not the
driver name. So it shouldn't be used in places where a driver name is
wanted, e.g. when reporting a test failure or when checking whether the
driver is the generic driver or not.
Fix this for the skcipher algorithm tests by getting the driver name
from the crypto_skcipher that actually got allocated.
