Subject: Bluetooth: hci_sync: Don't remove connected devices from accept list
Patch-mainline: v6.0-rc1
Git-commit: 6828b58307a92d6b626d4d1421ab7db6db125ba5
References: jsc#PED-1407

These devices are likely going to be reprogrammed when disconnected so
this avoid a whole bunch of commands attempt to remove and the add back
to the list.
