gdb/tui: make use of a scoped_restore

Make use of a scoped_restore object in tui_mld_read_key instead of
doing a manual save/restore.

I don't think the existing code can throw an exception, so this is
just a cleanup rather than a bug fix.

There should be no user visible changes after this commit.
