TEST 11 unlinks the URB read request for N times. When host and gadget
both initialize pattern 1 (mod 63) data series to do IN transfer, the
host side function should check the data buffer if it is as mod 63
series, because the data packet which host receivced will follow
pattern 1. So this patch adds this checking action.
