Robin Murphy 3238c359ac arm64: dma-mapping: Fix FORCE_CONTIGUOUS buffer clearing 
We need to invalidate the caches *before* clearing the buffer via the
non-cacheable alias, else in the worst case __dma_flush_area() may
write back dirty lines over the top of our nice new zeros.

Fixes: dd65a941f6 ("arm64: dma-mapping: clear buffers allocated with FORCE_CONTIGUOUS flag")
