BLIS: Errors in Netlib LAPACK Tests

Zen4 kernel bli_damaxv_zen_int_avx512 is causing incorrect results in
the netlib LAPACK tests, specifically in:

./xlintstd < ../dtest.in > dtest.out

in the TESTING/LIN directory. Given time constraints, i.e. the need to
finalize code for AOCL 4.0 release, disable calls to AVX512 kernel
(i.e. always use the AVX2 kernel) for now, and aim to correct
bli_damaxv_zen_int_avx512 for AOCL 4.1.
