drm/xe: Fix format specifier for printing pointer differences

GCC and clang warn (or error with CONFIG_WERROR=y / W=e) several times
when targeting 32-bit platforms along the lines of

  drivers/gpu/drm/xe/xe_lrc.c: In function 'dump_mi_command':

Use the '%tx' specifier for printing pointer differences, which clears
up the warnings for 32-bit platforms while introducing no regressions
for 64-bit platforms.
