i2c: Ignore the return value of i2c_del_mux_adapter()
i2c_del_mux_adapter() always returns 0. So all checks testing whether it will be non zero will always evaluate to false and the conditional code is dead code. This patch updates all callers of i2c_del_mux_adapter() to ignore its return value and assume that it will always succeed (which it will). A subsequent patch will make the return type of i2c_del_mux_adapter() void.
