[PATCH] xfs_db: reset metadump output flag

["Darrick J. Wong" <darrick.wong@oracle.com>]

On the off chance that someone runs metadump more than once with the
metadump file going to stdout and then not stdout, the stdout_metadump
variable will not be reset before the second invocation.  Clear the
status variable when we undo the stdout redirection.
