Subject: [PATCH] dma-buf: Don't use typeof in va_arg

Fix following coccicheck warning:
./drivers/dma-buf/st-dma-fence-unwrap.c:75:39-45: ERROR: reference preceded by free on line 70

Use 'struct dma_fence *' instead of 'typeof(*fences)' to avoid this
warning and also fix other 'typeof(*fences)' to make them consistent.

Fixes: 0c5064fa8d5a ("dma-buf: cleanup dma_fence_unwrap selftest v2")
