    virtio-mem: Correct format specifier mismatch for RISC-V
    
    This likely affects other, less popular host architectures as well.
    Less common host architectures under linux get QEMU_VMALLOC_ALIGN (from
    which VIRTIO_MEM_MIN_BLOCK_SIZE is derived) define to a variable of
    type uintptr, which isn't compatible with the format specifier used to
    print a user message. Since this particular usage of the underlying data
    seems unique to this file, the simple fix is to just cast
    QEMU_VMALLOC_ALIGN to uint32_t, which corresponds to the format specifier
    used.
