usb: gadget: zynq: Fix usb ethernet gadget probe error

This patch is based on the below commit
"usb: gadget: add "maxpacket_limit" field to struct usb_ep"
(sha1:e117e742d310683b410951faeab4b13b6c3c609f)

Value of "maxpacket_limit" should be set in UDC driver probe function, using
usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function
set choosen value to both "maxpacket_limit" and "maxpacket" fields.
