[REDIR] Fix popredir on abnormal exit from built-in
Just like the poplocalvar problem recently fixed, redirections can also be leaked in case of an abnormal exit. This patch fixes it using the same method as poplocalvar, by storing the previous redirection state and restoring to that point. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
