USB: core: Change usb_get_device_descriptor() API
The usb_get_device_descriptor() routine reads the device descriptor
from the udev device and stores it directly in udev->descriptor. This
interface is error prone, because the USB subsystem expects in-memory
copies of a device's descriptors to be immutable once the device has
been initialized.
The interface is changed so that the device descriptor is left in a
kmalloc-ed buffer, not copied into the usb_device structure. A
pointer to the buffer is returned to the caller, who is then
responsible for kfree-ing it. The corresponding changes needed in the
various callers are fairly small.
