Revert "crypto: api - Disallow identical driver names"

This reverts commit 462c383e732fa99c60aff711c43ec9d6eb27921e 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.
