zephyr: Unbonded peripheral gets 'Tx Buffer Overflow' when erasing bond on master

Describe the bug

[00709206] <err> bt_ctlr_hci: Tx Buffer Overflow
[00709206] <err> bt_hci_core: assert: 'bt_hci_evt_is_prio(hdr->evt)' failed

To Reproduce Steps to reproduce the behavior:

1. Bond master and peripheral
2. Remove bonds on peripheral
3. Observe peripheral disconnecting
4. Since master still has peripheral bonded it tries to reconnect
5. Connection is established and security start is called (that will fail as peripheral does not have bond)
6. When security fails and peripheral disconnects observe devices go back to point 4
7. At some point once devices are connected and security start is in progress remove bonds on central
8. Observe crash on peripheral; central is unaffected (disconnects and has bonds removed)

Expected behavior No crash. Central should be able to erase its bonds without effect on peripheral.

Impact Showstopper
