[ 13/22] usb: dwc3: gadget: fix ep->maxburst for ep0

[Greg Kroah-Hartman]

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Pratyush Anand <pratyush.anand@xxxxxx>

commit 6048e4c69d80600baba35856651056860d5d8f5a upstream.

dwc3_gadget_set_ep_config expects maxburst as incremented by 1. So, by
default initialize ep->maxburst to 1 for ep0.
