[PATCH v3 18/19] refs.c: free the transaction before returning when number of updates is 0

[Ronnie Sahlberg]

We have to free the transaction before returning in the early check for
'return early if number of updates == 0' or else the following code would
create a memory leak with the transaction never being freed :
   t = ref_transaction_begin()
   ref_transaction_commit(t)
