usb: cdns3: fix incorrect calculation of ep_buf_size when more than one config
Previously, the cdns3_gadget_check_config() function in the cdns3 driver
mistakenly calculated the ep_buf_size by considering only one
configuration's endpoint information because "claimed" will be clear after
call usb_gadget_check_config().
The fix involves checking the private flags EP_CLAIMED instead of relying
on the "claimed" flag.
