With recent next(next-20200621) af_alg02/05 tests fail while running on POWER9
PowerVM LPAR.

Results from  5.8.0-rc1-next-20200622
# ./af_alg02
tst_test.c:1096: INFO: Timeout per run is 0h 00m 20s
af_alg02.c:52: BROK: Timed out while reading from request socket.
#

5.8.0-rc1-next-20200618 was good. The test case ran fine.

Root cause analysis point to following commit:

commit f3c802a1f30013f8f723b62d7fa49eb9e991da23
    crypto: algif_aead - Only wake up when ctx->more is zero

Reverting this commit allows the test to PASS.

Results after reverting the mentioned commit:

# uname -r
5.8.0-rc1-next-20200622-dirty
# ./af_alg02 
tst_test.c:1096: INFO: Timeout per run is 0h 00m 20s
af_alg02.c:33: PASS: Successfully "encrypted" an empty message
#
# ./af_alg05
tst_test.c:1096: INFO: Timeout per run is 0h 05m 00s
af_alg05.c:34: PASS: read() expectedly failed with EINVAL
# 

Thanks
