Mapgen: Don't spread light of nodes outside the desired area

Browse Source 
This fixes #3935, a regression from 0338c2e.
An 'optimization' was performed where an index for the VoxelManip being
operated on was mistakenly used for bounds checking within the incorrect
VoxelArea, namely, the area wherein light should be spread.
