progress: check for ui.quiet and ui.debugflag before we write stable

progress: check for ui.quiet and ui.debugflag before we write

ui.quiet and ui.debugflag are not initialized during uisetup and
reposetup.  progressui is always initialized, therefore we have to check
during write() if ui.quiet is set or not.
