[PATCH] Bluetooth: bring device down when closing HCI_CHANNEL_USER socket

When a HCI_CHANNEL_USER socket is open and should be closed we first try to close the
device which will fail as hci_dev_close checks for HCI_CHANNEL_USER being set and if it is
it just fails to close the device. Clearing the HCI_CHANNEL_USER flag first before trying
to close the device fixes this.
