Bluetooth: hci_sync: Fix accept_list when attempting to suspend

[ Upstream commit e5469adb2a7e930d96813316592302d9f8f1df4e ]

During suspend, only wakeable devices can be in acceptlist, so if the
device was previously added it needs to be removed otherwise the device
can end up waking up the system prematurely.
