[PATCH] crypto/qat: fix build when no openssl exists

[Ciara Power <ciara.power@intel.com>]

Previously some compilation errors existed when no openssl
was installed on the system, and intel-ipsec-mb was installed,
due to missing headers and macros.

This patch fixes the issue by adding in extra ifdefs around openssl
specific code paths, and by adding the relevant macros explicitly
in QAT code so it does not depend on openssl at all.

Fixes: ca0ba0e48129 ("crypto/qat: default to IPsec MB for computations")
