[esp32_ble_tracker] Restart BLE scan after OTA failure

Browse Source 
When OTA starts, stop_scan() is called which clears the scan_continuous_
flag. If OTA fails or aborts, the scan was never restarted because
scan_continuous_ was already false. This left the device without BLE
scanning until reboot.

Save the scan_continuous_ state before stopping and restore it on
OTA_ERROR or OTA_ABORT to resume scanning.
