WINGs: Removed checks for code that can't fail

In the function 'wdefaultspathfordomain' there was a check to make sure the
generated path would fit in the allocated area, but this allocated area is
sized precisely to fit the path, so it cannot fail.

In the function 'getCurrentFileName' there were checks to make sure the
generated result string would fit in the allocated area, but this allocated
area is sized precisely to fit the path, so it cannot fail.
