[ Upstream commit 117647ff936e2d9684cc881d87c0291f46669c20 ]
This fixes a typo where the intent was to assign to 'j' in order to skip some number of bits in the dirty bitmap for a guest. The effect of the typo is benign since it means we just iterate through all the bits rather than skipping bits which we know will be zero. This issue was found by Coverity.
