radeonsi: init sctx->dma_copy before using it

Commit a1378639ab19 reordered context functions initializations but broke
sctx->b.resource_copy_region init when using AMD_DEBUG=forcedma.

In this case sctx->dma_copy was assigned a value after being used in:
   sctx->b.resource_copy_region = sctx->dma_copy;

This commit moves the FORCE_DMA special case after sctx->dma_copy initialization.
