Subject: [PATCH] Fix crash on xrun-reset when recording

Since 80c11a763a4 the GUI is notified when the xrun counter
is reset (previously the rec-ui xrun counter never returned
to zero).

However when create-xrun-marker is enabled ARDOUR_UI::xrun_handler
tried to create a marker at -1 which causes various issues.
