[ Upstream commit cbde979b33fa16e06dadc2c81093699a2bc787db ]
As we missed to detach HCI, while entering power off or hibernation, an extra hci interface gets created whenever system is woken up, to avoid this we added hci_detach() in rsi_disconnect(), rsi_freeze(), and rsi_shutdown() functions which are invoked for these tests. This patch fixes the issue
