From: Clancy Shang <clancy.shang@quectel.com>

According to Bluetooth Core Specification Version 5.4 | Vol 4, Part E,
7.8.38, if there is an existing entry in the resolving list with the same
non-zero Peer_IRK, the Controller should return the error code Invalid
HCI Command Parameters (0x12), so fix it.

Test environment:
I tested with the game controller device, and the steps are as follows:
1. The game controller device enters advertising pairing mode and then
   connects.
2. Disconnect.
3. Make the hand shank enter advertising pairing mode again and then
   reconnect.
4. Reproduce.
The step one and step four, the game controller device is the same device
but with a different privacy static address, causing the same IRK.

There could be some trouble if it is fixed in the kernel.
Firstly, there would be two devices in the paired list, but only the latest
device can be conneted. Actually they are the same device.
Secondly, the display will show two devices too.
