Issue1: If the concurrent transaction was aborted then in CATCH block
we were not freeing the memory of the toast_has, and it was causing
the assert that after the stream is complete txn->size != 0.
Issue2: After streaming is complete we set the txn->final_lsn and we
remember that in the local variable, But mistakenly it was remembered
in local TRY block variable so if there is a concurrent abort in the
CATCH block the variable value is always a zero. So after streaming
the final_lsn were becoming 0 and that was asserting.
