drm/xe: Fix uninitialized return value from xe_validation_guard()

the DEFINE_CLASS() macro creates an inline function and
the init args are passed down to it; since _ret is passed as an int,
whatever value is set inside the function is not visible to the caller.
Pass _ret as a pointer so its value propagates to the caller.
