crypto: testmgr - Move crypto_simd_disabled_for_test out

As testmgr is part of cryptomgr which was designed to be unloadable
as a module, it shouldn't export any symbols for other crypto
modules to use as that would prevent it from being unloaded. All
its functionality is meant to be accessed through notifiers.

The symbol crypto_simd_disabled_for_test was added to testmgr
which caused it to be pinned as a module if its users were also
loaded. This patch moves it out of testmgr and into crypto/algapi.c
so cryptomgr can again be unloaded and replaced on demand.

crypto: testmgr - Only disable migration in crypto_disable_simd_for_test()

crypto_disable_simd_for_test() disables preemption in order to receive a
stable per-CPU variable which it needs to modify in order to alter
crypto_simd_usable() results.

This can also be achived by migrate_disable() which forbidds CPU
migrations but allows the task to be preempted. The latter is important
for PREEMPT_RT since operation like skcipher_walk_first() may allocate
memory which must not happen with disabled preemption on PREEMPT_RT.

Use migrate_disable() in crypto_disable_simd_for_test() to achieve a
stable per-CPU pointer.

crypto: blake2s - remove shash module

[ Upstream commit 2d16803c562ecc644803d42ba98a8e0aef9c014e ]

BLAKE2s has no currently known use as an shash. Just remove all of this
unnecessary plumbing. Removing this shash was something we talked about
back when we were making BLAKE2s a built-in, but I simply never got
around to doing it. So this completes that project.

Importantly, this fixs a bug in which the lib code depends on
crypto_simd_disabled_for_test, causing linker errors.

Also add more alignment tests to the selftests and compare SIMD and
non-SIMD compression functions, to make up for what we lose from
testmgr.c.

crypto: testmgr - WARN on test failure

Currently, by default crypto self-test failures only result in a
pr_warn() message and an "unknown" status in /proc/crypto. Both of
these are easy to miss. There is also an option to panic the kernel
when a test fails, but that can't be the default behavior.

A crypto self-test failure always indicates a kernel bug, however, and
there's already a standard way to report (recoverable) kernel bugs --
the WARN() family of macros. WARNs are noisier and harder to miss, and
existing test systems already know to look for them in dmesg or via
/proc/sys/kernel/tainted.

Therefore, call WARN() when an algorithm fails its self-tests.
