The first evp_generic_fetch() always fail in UEFI sys due to wrong return of ossl_config_int()

[liyi77]

ossl_config_int() alway return 0 on the first call in UEFI system.

crypto/conf/conf_sap.c L44
int ossl_config_int(const OPENSSL_INIT_SETTINGS *settings)
{
    int ret = 0;
......
#ifndef OPENSSL_SYS_UEFI
    ret = CONF_modules_load_file(filename, appname, flags);
#endif
    openssl_configured = 1;
    return ret;
}

Then the first call of evp_generic_fetch() will fail due to ossl_method_store_fetch() fail:

int ossl_method_store_fetch(OSSL_METHOD_STORE *store,
                            int nid, const char *prop_query,
                            const OSSL_PROVIDER **prov_rw, void **method)
{
......
    if (!OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CONFIG, NULL))
        return 0; // First call always return 0 here
.....
}

ret only used to check return value of CONF_modules_load_file(), should set it to 1 if in UEFI system.
