Sarah Sharp 1624ae1c19 USB: xhci: Fix issue with set interface after stall. 
When the USB core installs a new interface, it unconditionally clears the
halts on all the endpoints on the new interface.  Usually the xHCI host
needs to know when an endpoint is reset, so it can change its internal
endpoint state.  In this case, it doesn't care, because the endpoints were
never halted in the first place.

To avoid issuing a redundant Reset Endpoint command, the xHCI driver looks
at xhci_virt_ep->stopped_td to determine if the endpoint was actually
halted.  However, the functions that handle the stall never set that
variable to NULL after it dealt with the stall.  So if an endpoint stalled
and a Reset Endpoint command completed, and then the class driver tried to
install a new alternate setting, the xHCI driver would access the old
xhci_virt_ep->stopped_td pointer.  A similar problem occurs if the
endpoint has been stopped to cancel a transfer.
