This failure is in one of the randomly generated test cases.  If it doesn't
reproduce reliably, you can set cryptomgr.fuzz_iterations=1000 on the kernel
command line (increased from the default 100).

It is confusing that it says just "sha1".  This seems to be a quirk specific to
how tcrypt calls alg_test().  It's probably really testing "sha1-sun4i-ss".
I guess that testmgr.c should be using the actual cra_driver_name in the log
messages, not the 'driver' string that was passed into alg_test().
