Patches for static check on geo_ops.c

Grzegorz Jaskiewicz wonderful static checker coughed up 5 errors in
geo_ops.c.  None of them of any particular excitement or of earth
shattering nature. A patch is attached below that should correct these.
(The more little issue we eliminate, the more the large ones will stand
out.)
