tier: Demotion failed if the file was renamed when it was in cold

During migration if the file is present we just open the file
in hashed subvol. Now if the linkfile present on hashed is just
linkfile to another subvol, we actually open in hashed subvol.

But subsequent operation will go to linkto subvol ie,
to non-hashed subvol. This operation will get failed
since we haven't opened d on non-hashed.
