Commit Message:
WII: Fix CLUT8 texture format handling

Reset _pfGameTexture when switching back to CLUT8 modes.
Without this, the backend could incorrectly keep the previous RGB565 texture format and use an invalid conversion path, resulting in black screens.
Also avoid a possible double free when _gamePixelsTexture and _gamePixels point to the same buffer.
