Subject: Btrfs: fix invalid reference in replace_path

From: Liu Bo <bo.li.liu@oracle.com>

commit 264813acb1c756aebc337b16b832604a0c9aadaf upstream.

Dan Carpenter's static checker has found this error, it's introduced by
commit 64c043de466d
("Btrfs: fix up read_tree_block to return proper error")

It's really supposed to 'break' the loop on error like others.
