Subject: [PATCH] usb: gadget: udc: s3c2410_udc: remove NULL check in s3c2410_udc_nuke()

No need to check the address of queue which is a member of struct
s3c2410_ep.

struct s3c2410_ep {
	struct list_head                queue;
	......
};

This fixes a coccicheck warning:

drivers/usb/gadget/udc/s3c2410_udc.c:255:1-3: ERROR: test of a
variable/field address
