Bluetooth: btusb: Fix not being able to reconnect after suspend
This partially reverts 81b3e33bb054 ("Bluetooth: btusb: Don't fail
external suspend requests") as it introduced a call to hci_suspend_dev
that assumes the system-suspend which doesn't work well when just the
device is being suspended because wakeup flag is only set for remote
devices that can wakeup the system.
