mlxsw: thermal: Fix null dereference of NULL temperature parameter

Browse source

The call to mlxsw_thermal_module_temp_and_thresholds_get passes a NULL
pointer for the temperature and this can be dereferenced in this function
if the mlxsw_reg_query call fails.  The simplist fix is to pass the
address of dummy temperature variable instead of a NULL pointer.

Addresses-Coverity: ("Explicit null dereferenced")
