4.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Liu Bo <bo.li.liu@xxxxxxxxxx>
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.
