Btrfs: close devices on all error paths in open_ctree()
Fix a bug introduced by 7e662854 where we would leave devices busy on certain error paths in open_ctree(). fs_info is guaranteed to be non-NULL now so it's safe to dereference it on all error paths. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
