Sarah Sharp fa75ac379e xhci: Reject double add of active endpoints.
While trying to switch a UAS device from the BOT configuration to the UAS
configuration via the bConfigurationValue file, Tanya ran into an issue in
the USB core.  usb_disable_device() sets entries in udev->ep_out and
udev->ep_out to NULL, but doesn't call into the xHCI bandwidth management
functions to remove the BOT configuration endpoints from the xHCI host's
internal structures.

The USB core would then attempt to add endpoints for the UAS
configuration, and some of the endpoints had the same address as endpoints
in the BOT configuration.  The xHCI driver blindly added the endpoints
again, but the xHCI host controller rejected the Configure Endpoint
command because active endpoints were added without being dropped.

Make the xHCI driver reject calls to xhci_add_endpoint() that attempt to
add active endpoints without first calling xhci_drop_endpoint().

This should be backported to kernels as old as 2.6.31.
