Fix IndexOutOfBoundsException while silent provisioning check
- If hostpot off, we receive result through HotspotOffReceiver.
Sometimes, during provisioning, we're used to receive this.
In this case, we don't care.
After provisioning, we'll receive the intent again.
- In stress test,
index is sometimes invalid, equals to mCurrentTethers.size().
So, when provisioning, We check whether index is valid or not.
