The default behaviour for SGX support in upstream Linux is to have /dev/sgx_provision & /dev/sgx_enclave device nodes[1], rather than /dev/sgx/provision & /dev/sgx/enclave. The code should prefer opening the current default device nodes first, with the other paths as the fallback, so the common case will be an immediate success.
