FAILED: patch "[PATCH] fs/remap: constrain dedupe of EOF blocks" failed to apply to 5.4-stable tree

Fix this by constraining the EOF block matching to only match against other EOF blocks that have identical EOF offsets and data. This allows "whole file dedupe" to continue to work without allowing eof blocks to randomly match against partial full blocks with the same data.
