staging: emxx_udc: Fix passing of NULL to dma_alloc_coherent()

Browse source

In nbu2ss_eq_queue() memory is allocated with dma_alloc_coherent(),
though, strangely, NULL is passed as the struct device* argument. Pass
the UDC's device instead. Fix up the corresponding call to
dma_free_coherent() in the same way.

Build-tested on x86 only.
