esp_efuse_utility_load_efuses_from_flash() read emul_efuse as an encrypted partition, but that is not correct, this partition was never encrypted. Need to read it as not encrypted partition. Fxed the case: If FE is already on then EFUSE VIRT mode can work with it. Closes https://github.com/espressif/esp-idf/issues/10929
