USB: cancel pending Set-Config requests if userspace gets there first
This patch (as1195) eliminates a potential problem identified by
Oliver Neukum. When a driver queues an asynchronous Set-Config
request using usb_driver_set_configuration(), the request should be
cancelled if userspace changes the configuration first. The patch
introduces a linked list of pending async Set-Config requests, and
uses it to invalidate the requests for a particular device whenever
that device's configuration is set.
