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, ...
I've added a few checks to prevent that.
Fixes: 13107c60681f ("misc: pci_endpoint_test: Add support to provide aligned buffer addresses")
