OSSL_STORE_error() returns true at EOF when no error occurred, leading to "error:success"

In the code below, CA certificates are read from a PEM file. At the end of the read, OSSL_STORE_load() returns NULL as expected, but in the code that follows, OSSL_STORE_error() returns true.

This leads to the following being logged:

failed: unable to create new TLS context: 0 (Success)

OSSL_STORE_error() should only return true of an error actually occurred - EOF is not an error.

				while ((info = OSSL_STORE_load( sctx ))) {
					switch (OSSL_STORE_INFO_get_type( info )) {
					case OSSL_STORE_INFO_CERT:
						X509 *cert = OSSL_STORE_INFO_get0_CERT( info );
						X509_STORE *store = SSL_CTX_get_cert_store( ctx );
						if ( !X509_STORE_add_cert( store, cert ) ) {
							Debug1( LDAP_DEBUG_ANY,
								"TLS: could not use certificate from uri `%s'.\n",
								lo->ldo_tls_cacerturis[i] );
							tlso_report_error( errmsg );
							OSSL_STORE_close( sctx );
							return -1;
						}
						if ( is_server ) {
							STACK_OF(X509_NAME) *ca_list = SSL_CTX_get_client_CA_list( ctx );

								X509_NAME *xn = X509_get_subject_name( cert );
								if ( xn )
									xn = X509_NAME_dup( xn );
								if ( xn )
									sk_X509_NAME_push( ca_list, xn );
							}
						}
						break;
					default:
						/* ignore other types */
						break;
					}
					OSSL_STORE_INFO_free( info );
				}
				if (OSSL_STORE_error(sctx)) {
					Debug1( LDAP_DEBUG_ANY,
						"TLS: could not load from uri `%s'.\n",
						lo->ldo_tls_uris[i] );

					OSSL_STORE_close( sctx );
					return -1;
				}
				OSSL_STORE_close( sctx );

The reported entry points are OSSL_STORE_load() and OSSL_STORE_error(); start by tracing their EOF handling and locating the existing OSSL_STORE tests. Reproduce the PEM read shown in the issue, then verify that normal EOF is not reported as an error while genuine load failures still are.
