Michael Brown 9ff6d08bf5 [efi] Avoid infinite loops when asked to stop non-existent devices ...

Calling EDK2's OpenProtocol() with attributes BY_DRIVER|EXCLUSIVE will
call DisconnectController() in a loop to attempt to dislodge any
existing openers with attributes BY_DRIVER.  The loop will continue
indefinitely until either no such openers remain, or until
DisconnectController() returns an error.

If our driver binding protocol's Stop() method is ever called to
disconnect a device that we are not in fact driving, then return
EFI_DEVICE_ERROR rather than EFI_SUCCESS, in order to break this
potentially infinite loop.
