nvs_flash_init may return an error code in some cases, and applications should check this error code (or at least assert on it being ESP_OK, to make potential issues more immediately obvious). This change modifies all the examples which use NVS to check the error code. Most examples get a simple ESP_ERROR_CHECK assert, while NVS examples, OTA example, and NVS unit tests get a more verbose check which may be used in real applications.
