Btrfs: fix that error value is changed by mistake
In iterate_inodes_from_logical() the error result from extent_from_logical() is patched by mistake. Typically ENOENT is patched to EINVAL because (-ENOENT & BTRFS_EXTENT_FLAG_TREE_BLOCK) evaluates to true. Signed-off-by: Stefan Behrens <sbehrens@giantdisaster.de>
