drm/amd/display: Remove unnecessary assignments

[WHAT & HOW]
TimeForFetchingMetaPTE, TimeForFetchingRowInVBlank and
LinesToRequestPrefetchPixelData are local variables. They
are freed when CalculatePrefetchSchedule() ends and need
not clearing explicitly.

This fixes 21 UNUSED_VALUE issues reported by Coverity.
