crypto: testmgr - always print the actual driver name

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.

See https://lkml.kernel.org/r/20200910122248.GA22506@Red for an example where this caused a problem. The self-tests reported "alg: ahash: md5 test failed", but it wasn't mentioned which md5 implementation it was.

Fix this by getting the driver name from the crypto tfm object that actually got allocated.

Eric Biggers (4):
crypto: aead - add crypto_aead_driver_name()
crypto: testmgr - always print the actual hash driver name
crypto: testmgr - always print the actual AEAD driver name
crypto: testmgr - always print the actual skcipher driver name
