msm: vidc: Amend condition related to power save mode

Currently, instance load checking against
firmware populated capabilities of power saving mode
to trigger power saving mode.
If instance load is greater than max capabilities populated
by firmware then power saving mode is not set.
Remove max condition to enable low power mode even
when instance load is greater than max capabilities.
