hw/qxl: Fix format string errors

Fix format string errors causing compile failure on 32 bit hosts
when spice is enabled.

This fixes the easy parts of the 32 bit compile failures with
spice enabled. It leaves the following two warnings:
 hw/qxl.c: In function 'interface_release_resource':
 hw/qxl.c:627:46: error: cast to pointer from integer of different size
 hw/qxl.c: In function 'qxl_phys2virt':
 hw/qxl.c:1003:16: error: cast to pointer from integer of different size

which appear to be making deeper "pointers are 64 bits" assumptions
that I don't know enough about the spice code to suggest fixes for.
(Throwing in (intptr_t) casts suppresses the warning but seems a
bit icky...)

Could somebody else take a look at those, please?

Patch looks good.

Spice server doesn't work for 32 bit machines. So regardless of the
fix it should not be possible to enable it for 32 bit builds. I think
if it were to work then the casts you suggest would be the simplest
assumption, keeping the qxl device structs the same (64 bit address
fields).
