Don't send DISCARD after ExecAbortError in pipeline

The `EXECABORT` error type was added in Redis 2.6.5 and is returned from an
`EXEC` command to indicate that the transaction was aborted due to an invalid
command.  It is not necessary to call `DISCARD` after this error, and doing so
causes a "DISCARD without MULTI" error.
