commit 982555fc26f9d8bcdbd5f9db0378fe0682eb4188 upstream.
For isoc endpoint descriptor, the wMaxPacketSize is not real max packet
size (see Table 9-13. Standard Endpoint Descriptor, USB 2.0 specifcation),
it may contain the number of packet, so the real max packet should be
ep->desc->wMaxPacketSize && 0x7ff.
