tier:delete the linkfile if data file creation fails
If we are creating data file in a hot subvolume
then we will create a linkfile in cold subvolume.
Linkfile creation happens first. If linkfile creation
was successful and data file creation failed, then
linkfile in cold subvolume will become stale
This patch will delete the linkfile as well, if data
file creation fails
Also this code duplicates dht_create to make tier_create
