btrfs: use error code returned by btrfs_read_fs_root_no_name in search ioctl
btrfs_read_fs_root_no_name() may return ERR_PTR(-ENOENT) or
ERR_PTR(-ENOMEM) and therefore search_ioctl() and
btrfs_search_path_in_tree() should use PTR_ERR() instead of -ENOENT,
which all other callers of btrfs_read_fs_root_no_name() do.
Drop the error message as it would be confusing, the caller of ioctl
will likely interpret the error code and not look into the syslog.
