BUG/MEDIUM: cli: Prevent double free in CLI ACL lookup

The memory is released by cli_release_mlook, which also properly sets the
pointer to NULL. This was introduced with a big code reorganization
involving moving to the new keyword registration form in commit ad8be61c7.

This fix needs to be backported to 1.7.
