When looking the stored result for a cached path node, if the stored
result is valid and has a value of true, we must update all the nodes for
all levels below it with a result of true as well. This is necessary when
moving from one leaf in the fs tree to the next one, as well as when
moving from a node at any level to the next node at the same level.
Currently this logic is missing as it was somehow forgotten by a recent
patch with the subject: "btrfs: speedup checking for extent sharedness
during fiemap".
This adds the missing logic, which is the counter part to what we do
when adding a shared node to the cache at store_backref_shared_cache().
Fixes: 12a824dc67a6 ("btrfs: speedup checking for extent sharedness during fiemap")
