drm: i915: Change fault type to unsigned long

Fault is currently of type u32 and with the introduction of the
generalized vdso/page.h we trigger the error below:

drivers/gpu/drm/i915/gt/intel_gt_print.h:29:36: error: format ‘%lx’ expects
argument of type ‘long unsigned int’, but argument 6 has type ‘u32’ {aka
‘unsigned int’} [-Werror=format=]

This happens because the type of PAGE_MASK depends on the architecture.

Prevent the compilation error changing the 'fault' type to unsigned
long.
