Mayank Rana b3207c65df usb: xhci: Handle error condition in xhci_stop_device() ... xhci_stop_device() calls xhci_queue_stop_endpoint() multiple times without checking the return value. xhci_queue_stop_endpoint() can return error if the HC is already halted or unable to queue commands. This can cause a deadlock condition as xhci_stop_device() would end up waiting indefinitely for a completion for the command that didn't get queued. Fix this by checking the return value and bailing out of xhci_stop_device() in case of error. This patch happens to fix potential memory leaks of the allocated command structures as well.
