Reyad Attiyat 46df9dedab HID: usbhid: Use flag HID_DISCONNECTED when a usb device is removed 
Set disconnected flag in struct usbhid when a usb device is removed. Check for
disconnected flag before sending urb requests. This prevents a kernel panic
when a hid driver calls hid_hw_request() after removing a usb device.

 BUG: unable to handle kernel NULL pointer dereference at 0000000000000058
