cluster/dht: Don't restore entry when only one subvolume is present
Problem:
When rmdir fails with op_errno other than ENOENT/EACCES then self-heal
is attempted with zeroed-out stbuf. Only ia_type is filled from inode,
when the self-heal progresses, it sees that the directory is still
present and performs setattr with all valid flags set to '1' so the
file will be owned by root:root and the time goes to epoch
Fix:
This fixes the problem only in dht with single subvolume. Just don't
perform self-heal when there is a single subvolume.
