fs: btrfs: Prevent error pointer dereference in list_subvolums()
If btrfs_read_fs_root() fails with -ENOENT, then we go to the next
entry. Fine. But if it fails for a different reason then we need
to clean up and return an error code. In the current code it
doesn't clean up but instead dereferences "root" and crashes.
