usb: wusbcore: combine iso transfer result frame reads when possible
When reading the transfer result data for an isochronous in request, if
the current frame actual_length is contiguous with the next frame and
actual_length is a multiple of the DTI endpoint max packet size, combine
the current frame with the next frame in a single URB. This reduces the
number of URBs that must be submitted in that case which increases
performance and reduces CPU interrupt overhead.
