usb: gadgetfs: restrict upper bound on device configuration size
commit 0994b0a257557e18ee8f0b7c5f0f73fe2b54eec1 upstream.
Andrey Konovalov reported that we were not properly checking the upper
limit before of a device configuration size before calling
memdup_user(), which could cause some problems.
So set the upper limit to PAGE_SIZE * 4, which should be good enough for
all devices.
