Fixed performance regression in ShadowViews layout process

Browse Source 
Summary:
This fixes perf regression which was introduced by recent refactoring of the layout process.
That is how it used to be:
114c258045/React/Views/RCTShadowView.m (L160-L166)
Note: We have to resert this flag in indication that we already applied those changes and we don't need to traverse this subtree until it is changed again.
