[PATCH, RESEND] usb: gadget: udc: atmel: fix debug output

The debug output now contains the wrong variable, as seen from the compiler
warning:

drivers/usb/gadget/udc/atmel_usba_udc.c: In function 'usba_ep_enable':
drivers/usb/gadget/udc/atmel_usba_udc.c:632:550: error: 'ept_cfg' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  DBG(DBG_ERR, "%s: EPT_CFG = 0x%lx (maxpacket = %lu)\n",

This changes the debug output the same way as the other code.

Originally sent on Feb 1, but this was never picked up. Resending it now,
as it is one of the few remaining build regressions in linux-next compared
to linux-4.10.
