dma-mapping: fix tracing dma_alloc/free with vmalloc'd memory
Not all virtual addresses have physical addresses, such as if they were
vmalloc'd. Just trace the virtual address instead of trying to trace a
physical address. This aligns with the API, and is good enough to
associate dma_alloc with dma_free.
Fixes: 038eb433dc14 ("dma-mapping: add tracing for dma-mapping API calls")
