In xhci_get_port_bandwidth(), we use a variable-length array to construct the buffer to send back to the guest. Avoid the VLA by using dma_memory_set() to directly request the memory system to fill the guest memory with a string of '80's. The codebase has very few VLAs, and if we can get rid of them all we can make the compiler error on new additions. This is a defensive measure against security bugs where an on-stack dynamic allocation isn't correctly size-checked (e.g. CVE-2021-3527).
