Because there are limits to what benders can do. They are not gods. A firebender can't remove heat to cool past a certain point. The freezing point from lava/magma to rock can be several hundred degrees. The freezing point from water to ice is obviously much less, at 32 degrees. I am talking Fahrenheit btw.

Anyways, the point is a firebender doesn't have to cool nearly as much to cool the lava/magma to rock, so it is within their limits. However, water's freezing point is well beyond those limits and into waterbender territory, as waterbenders freeze things.
