Subject: [PATCH] WineD3D: Leave the fog state handler after disabling fog

If D3DRS_FOGENABLE is false GL_FOG is disabled, and state_fog can be
left immediately because everything else done in there will have no
effect. It seems that I've been a it sloppy when I wrote that code, so I
forgot the return.

The existing code works because there is a double check on fogenable.
Depending on the fog parameters in the stateblock and supported opengl
extensions, fogging may be disabled if GL_EXT_fog_coord is not
supported. A check for fogenable after those checks caught disabling the
fog.
