btrfs: tree-log: check btrfs_lookup_data_extent return value
[ Upstream commit 3736127a3aa805602b7a2ad60ec9cfce68065fbb ]
Function btrfs_lookup_data_extent calls btrfs_search_slot to verify if
the EXTENT_ITEM exists in the extent tree. btrfs_search_slot can return
values bellow zero if an error happened.
Function replay_one_extent currently checks if the search found
something (0 returned) and increments the reference, and if not, it
seems to evaluate as 'not found'.
Fix the condition by checking if the value was bellow zero and return
early.
