usb: chipidea: udc: fix memory leak in _ep_nuke

Browse Source 
commit 7ca2cd291f upstream.

In hardware_enqueue code adds one extra td with dma_pool_alloc if
mReq->req.zero is true. When _ep_nuke will be called for that endpoint,
dma_pool_free will not be called to free that memory again. That patch
fixes this.
