Mahavir Jain b3aff63db4 app_update: fix intermittent failure with firmware updates
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.
