[PATCH] USB core and HCDs: don't put_device while atomic

This patch (as640) removes several put_device and the corresponding
get_device calls from the USB core and HCDs.  Some of the puts were done
in atomic contexts, and none of them are needed since the core now
guarantees that every endpoint will be disabled and every URB completed
before a USB device is released.
