USB: gadget: ci13xxx_udc: Fix bug in nuking the control OUT endpoint

ci13xxx_udc controller driver exposes EP0 In as control endpoint to
function drivers.  Function drivers request both IN and OUT control
data transfers on EP0 In.  Controller driver internally uses EP0 Out
for queuing/retiring OUT control endpoint requests by checking the
control transfer direction.  Do the same for nuking and dequeuing.
