fix HAS_MULTIP_6675 null condition & compiler warning

Browse source 
In temperature.h if HAS_MULTI_6675 does not have a 1 after it. HAS_MULTI_6675 is defined as NUL

In temperature.cpp  when Thermocouple is open the max6675_temp value is meant to have a TMAX * 4 so I added the pair of parentheses so the compiler would stop throwing a waring message about the statement being a binary statement.
