USB: gadget: fix req length in sourcesink_setup()
The recent commit 2edb11cbac fixed req->length in the composite_setup()
function, but that will cause all g_zero tests to fail like:
root#> ./testusb -D /proc/bus/usb/002/021 -t14 -c 15000 -s 256 -v 1
unknown speed /proc/bus/usb/002/021
/proc/bus/usb/002/021 test 14 --> 32 (Broken pipe)
We need to fix req->length in sourcesink_setup() as well to avoid this.
