[PATCH virt-viewer] Set freed variables to NULL in remote_viewer_start()

[Jonathon Jongsma <jjongsma@xxxxxxxxxx>]

Coverity warns that 'type' can sometimes be used or free after already having
been freed.  This can happen when open_recent_dialog is true and we jump back up
to the retry_dialog label.  To prevent this, make sure the freed variables are
set to NULL after freeing.
