avoid new "where are we?" panic

Browse Source 
savelev() gets run to clean up memory even if the player quits before
level 1 is created, and a change made yesterday panicked if it couldn't
figure out what level the hero is on.  Caught by entrez, again....

If not actually writing a level's file, don't panic if both u.uz and
g.uz_save are 0.  Having one of those be non-zero is only essential
when the level being processed is the Plane of Water or Plane of Air.
