richedit: Removed some conditions that are always taken.

ME_GetCursorCoordinates had two conditions that were always taken. The first condition was if(pCursor->pRun->type == diRun) was following an assertion making the exact same check. The next one, if(row), should always be taken, otherwise the richedit controls are in a corrupt state, therefore an assertion is more appropriate.
