Like done in commit eaa287069a ("drm/xe/guc_submit: Simplify and fix
diff calculation"), just use u32 for wrapping the value, which is
simpler and more correct: when wrapping on 32b, the accumulated value
was off by one.
Also, do not mix the u64 value from pmt with the u32 value used for the
calculation.
