Fix a segmentation fault error in the updateProperty method

Program received signal SIGSEGV, Segmentation fault.
Sensor::updateProperty (this=0x4f4ae0, interface=..., oldValue=@0x4f4b80: nan(0x8000000000000),
    newValue=@0x7efff778: nan(0x8000000000000), dbusPropertyName=0x47d567 "Value")
    at /usr/src/debug/dbus-sensors/0.1+gitAUTOINC+623723b9e8-r0/git/include/sensor.hpp:307

It was caused by a missing null pointer checking on a dBus interface
so this commit adds the null pointer checking. This case can be
happened on Tjmax and Tthrottle in CPU sensors that intentionally
removed sensorInterface to make itself as a hidden sensor.
