[PATCH i-g-t] tests/intel/xe_pm_residency: assert only if idle residency is lesser than elapsed time

[Riana Tauro]

When device is suspended (system suspend or runtime suspend),
device needs to be woken up to read residency.
Idle residency may increase above tolerance
based on the resume time, thus being greater than elapsed ms.

assert only if idle residency is less than elapsed time
and not within tolerance.
