speed: Fix execution of EdDSA measurement
Running 'openssl speed eddsa' fails with Doing 253 bits sign Ed25519 ops for 10s: EdDSA sign failure 000003FF9306C7D0:error:030000BC:digital envelope routines:EVP_DigestSign: final error:crypto/evp/m_sigver.c:585: -1 253 bits Ed25519 sign ops in 0.00s Doing 253 bits verify Ed25519 ops for 10s: EdDSA verify failure 000003FF9306C7D0:error:030000BC:digital envelope routines:EVP_DigestVerify: final error:crypto/evp/m_sigver.c:694: -1 253 bits Ed25519 verify ops in 0.00s This is because the EVP_DigestSign/Verify() calls in the EdDSA_sign/verify_loop() fail because the context has already been finalized by the previous EVP_DigestSign/Verify call during the EdDSA signature test done by speed_main(). This happens since commit 3fc2b7d where the EVP_DigestSign/Verify() functions have been changed to set a flag that the context has been finalized. Fix this by re-initializing the context using EVP_DigestSign/Verify() in the EdDSA_sign/verify_loop().
