Subject: btrfs: return value from btrfs_mark_extent_written() in case of error
From: Ritesh Harjani <riteshh@xxxxxxxxxxxxx>
commit e7b2ec3d3d4ebeb4cff7ae45cf430182fa6a49fb upstream.
We always return 0 even in case of an error in btrfs_mark_extent_written().
Fix it to return proper error value in case of a failure. All callers
handle it.
