[Freeciv-Dev] (PR#11589) Missing TILE_XY uses

["Benedict Adamson" <badamson@xxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=11589 >

When we changed from using x, y coordinates to indicate map positions, 
to using tile pointers, some of the AI logging functions were 
incorrectly updated. Instead of saying 'TILE_XY(ptile)' in the call to 
the logging function, they say 'ptile'. The resulting log message is 
garbaled. I guess there is a (very small) risk of a SEGV too.
