drm/xe/guc: Fix size_t print format

commit 213e242 upstream.

Use %zx format to print size_t to remove the following warning when
building for i386:

>> drivers/gpu/drm/xe/xe_guc_ct.c:1727:43: warning: format specifies type 'unsigned long' but the argument has type 'size_t' (aka 'unsigned int') [-Wformat]
    1727 |                         drm_printf(p, "[CTB].length: 0x%lx\n", snapshot->ctb_size);
         |                                                        ~~~     ^~~~~~~~~~~~~~~~~~
         |                                                        %zx
