btrfs: remove redundant path release when overwriting item during log replay

At overwrite_item() we have a redundant btrfs_release_path() just before
failing with -ENOMEM, as the caller who passed in the path will free it
and therefore also release any refcounts and locks on the extent buffers
of the path. So remove it.
