i2c: Make the return type of i2c_del_mux_adapter() void
i2c_del_mux_adapter always returns 0 and none of it current users check its return value anyway. It is also an essential requirement of the Linux device driver model, that functions which may be called from a device's remove callback to free resources provided by the device, are not allowed to fail. This is the case for i2c_del_mux_adapter(), so make its return type void to make the fact that it won't fail explicit.
