GlusterFS: Fix deadlock in volume clone

The create_cloned_volume path could deadlock due to
create_cloned_volume and create/delete_snapshot using the same
lock for synchronization.

Refactor the calls to create/delete snapshot to call the inner
method which does not use a lock.

Introduced by "06999f6 GlusterFS: Synchronize additional op..."
