bi4k8 faba25d197 logging: define CRIT_ERR_FREE and simplify CRIT_ERR 
it's surprising to pass 2 nullptr arguments at most of the callsites of a logging function, so instead let callers explicitly state whether they have auxiliary data to free

* Things to do:
* - Move decoding of GPU/MEM freqs to print_nvidia_value() using QUERY_SPECIAL
* so that all quirks are located there
* - Implement nvs->print_type to allow control over how the value is printed
* (int, float, temperature...)
*
* Showcase (conky.conf):
