rbd: split the parsing and deletion logic to its own functions.

Browse Source 
parseAndDeleteMigratedVolume() prviously clubbed the logic of
parsing of migration volume handle and then continued with the
deletion of the volume. however this commit split this
logic into two, ie parsing has been done in parseMigrationVolID()
and DeleteMigratedVolume() deletes the backend volume.
