Set misc_attr in the top level sgx_create_enclave if _create_enclave
fails. This provides the user with the platform's capabilities when
sgx_create_enclave fails for any reason other than a parameter error.
Previously the misc_attr was only set upon failure if build_image
failed, which was not helpful when sgx_create_enclave failed due to
an attribute error, e.g. misc_select, as the flow aborted before it
reached build_image.
