drm/sun4i: backend: Fix probe failure with multiple backends
Commit e0d072782c73 ("dma-mapping: introduce DMA range map, supplanting
dma_pfn_offset") introduced a regression in our code since the second
backed to probe will now get -EINVAL back from dma_direct_set_offset and
will prevent the entire DRM device from probing.
Ignore -EINVAL as a temporary measure to get it back working, before
removing that call entirely.
