Netdata not returning correct value for unknow variables (#6984)
* health_nan: fix result
The expression evaluate was keeping the value zero when there was a wrong variable,
but according our documentation the correct result would be NAN, this commit fixes this
* health_nan: mapping
* health_nan: Set variable
After few tests, I am setting the NAN value to the variable in the correct place
