BugLink: https://bugs.launchpad.net/bugs/1892822 commit 4f26433e upstream. While logging an inode, at copy_items(), if we fail to lookup the checksums for an extent we release the destination path, free the ins_data array and then return immediately. However a previous iteration of the for loop may have added checksums to the ordered_sums list, in which case we leak the memory used by them. So fix this by making sure we iterate the ordered_sums list and free all its checksums before returning.
