Bluetooth: hci_core: fix error handling in hci_register_dev()

[ Upstream commit 0d75da38e060d21f948b3df5f5e349c962cf1ed2 ]

If hci_register_suspend_notifier() returns error, the hdev and rfkill
are leaked. We could disregard the error and print a warning message
instead to avoid leaks, as it just means we won't be handing suspend
requests.
