[PATCH v2] fuzz: Display hexadecimal value with '0x' prefix

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

Use memory_region_size() to get the MemoryRegion size,
and display it with the '0x' prefix.

Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org>

v2:
- Use PRIx64 (lvivier)
- Use memory_region_size()
