Routine `spi_flash_cache2phys` sometimes return incorrect value, resulting in failure in getting currently running ota partition. This in turn aborts firmware update process.This issue was more prominent with SPIRAM enabled cases. Fix ensures proper cache guards during `spi_flash_cache2phys`, and also for few other similar APIs. In addition, `esp_ota_get_running_partition` has also been optimized to save currently running partition for subsequent invocations. Fixes https://github.com/espressif/esp-idf/issues/2451
