Subject: [PATCH] Revert "crypto: api - Disallow identical driver names"

This reverts commit a6fec6324f518991d63360693224b42e0ea3144f which is
commit 27016f75f5ed47e2d8e0ca75a8ff1f40bc1a5e27 upstream.

It is reported to cause problems in older kernels due to some crypto
drivers having the same name, so revert it here to fix the problems.
