[PATCH v2 1/2] virtio-mem: Change PRIx32 to PRIXPTR to fix compile error.

[Kaige Li <likaige@loongson.cn>]

When I compile qemu with such as:

git clone https://git.qemu.org/git/qemu.git
cd qemu
git submodule init
git submodule update --recursive
./configure
make

There is error log:

/home/LiKaige/qemu/hw/virtio/virtio-mem.c: In function ‘virtio_mem_set_block_size’:
/home/LiKaige/qemu/hw/virtio/virtio-mem.c:756:9: error: format ‘%x’ expects argument of type ‘unsigned int’, but argument 7 has type ‘uintptr_t’ [-Werror=format=]
         error_setg(errp, "'%s' property has to be at least 0x%" PRIx32, name,
         ^
cc1: all warnings being treated as errors
/home/LiKaige/qemu/rules.mak:69: recipe for target 'hw/virtio/virtio-mem.o' failed

So, change PRIx32 to PRIXPTR to fix this.
