drm/cma-helper: Release non-coherent memory with dma_free_noncoherent()
commit 995f54ea962e03ec08b8bc6a4fe11a32b420edd3 upstream.
The GEM CMA helpers allocate non-coherent (i.e., cached) backing storage
with dma_alloc_noncoherent(), but release it with dma_free_wc(). Fix this
with a call to dma_free_noncoherent(). Writecombining storage is still
released with dma_free_wc().
