red-replay-qxl: Fix replay on 32 bit systems

On 32 systems pointers are 32 bit while QXLPHYSICAL is always
64 bit.
Using pointer -> intptr_t -> QXLPHYSICAL conversion cause pointers
to have higher 32 bit set to 1 if the address is >= 0x80000000.
This is possible depending on address space.
The QXLPHYSICAL is split in 3 sections:
- slot ID;
- generation;
- virtual address.
Current utility using record file (spice-server-replay) set slot ID
and generation to 0 so if the higher bits become all 1 slot ID and
generation won't be 0 causing the utility to fail.
Use pointer -> uintptr_t -> QXLPHYSICAL conversion to avoid this
issue.
Note that for opposite conversion (QXLPHYSICAL_TO_PTR) the conversion
does not change, type is changed just for consistency.
