Dan Carpenter 343dc693f7 misc: pci_endpoint_test: Prevent some integer overflows
"size + max" can have an arithmetic overflow when we're allocating:

  orig_src_addr = dma_alloc_coherent(dev, size + alignment, ...

Add a few checks to prevent that.

Fixes: 13107c60681f ("misc: pci_endpoint_test: Add support to provide aligned buffer addresses")
