[PATCH] usb: dwc3: correct default value of maxburst

[Chanho Park <chanho61.park@xxxxxxxxxxx>]

This patch changes default value of maxburst to 1. When a connection is
established to highspeed, the maxburst is set to 0. So, we need to check and
change default value of the maxburst before setting up burst size of ep.
