hw/nvme: Avoid dynamic stack allocation
Instead of using a variable-length array in nvme_map_prp(),
allocate on the stack with a g_autofree pointer.
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).
