btrfs: remove BUG_ON(!eie) in find_parent_nodes
[ Upstream commit 9f05c09d6b
]
If we're looking for leafs that point to a data extent we want to record
the extent items that point at our bytenr. At this point we have the
reference and we know for a fact that this leaf should have a reference
to our bytenr. However if there's some sort of corruption we may not
find any references to our leaf, and thus could end up with eie == NULL.
Replace this BUG_ON() with an ASSERT() and then return -EUCLEAN for the
mortals.
