usb: dwc3: gadget: Check MaxPacketSize from descriptor



endpoint->maxpacket is not updated after setting the
usb_set_maxpacket_limit() on endpoint enable. The MaxPacketSize can be
different than the endpoint->maxpacket_limit.

DWC3 has been consistently using MaxPacketSize from the endpoint's
descriptor, so let's keep it consistent and use the MaxPacketSize from
the endpoint's descriptor instead.
