util: remove the deleteLock acquistion check for clone and snapshot

Browse Source 
At present while acquiring the deleteLock on the volume, we check
for ongoing clone and snapshot creation operations on the same.
Considering snapshot and clone controllers does not allow parent
volume deletion on subjected operations, we can be free from this
extra check.
