commit 89bb3dc13ac29a563f4e4c555e422882f64742bd upstream.
usb core avoids sending a Set-Interface altsetting 0 request after device
reset, and instead relies on calling usb_disable_interface() and
usb_enable_interface() to flush and reset host-side of those endpoints.
xHCI hosts allocate and set up endpoint ring buffers and host_ep->hcpriv
during usb_hcd_alloc_bandwidth() callback, which in this case is called
before flushing the endpoint in usb_disable_interface().
Call usb_disable_interface() before usb_hcd_alloc_bandwidth() to ensure
URBs are flushed before new ring buffers for the endpoints are allocated.
Otherwise host driver will attempt to find and remove old stale URBs
from a freshly allocated new ringbuffer.
