The value was written however, and update will be finished after re-initialization of nvs, provided that flash operation
doesn't fail again.

ESP_ERR_NVS_PAGE_FULL
ESP_ERR_NVS_INVALID_STATE
nvs_flash_init and nvs_open again, then retry.
ESP_ERR_NVS_INVALID_LENGTH
ESP_ERR_NVS_NO_FREE_PAGES
if NVS partition was truncated. Erase the whole partition and call nvs_flash_init again.
