This ID is meaningless outside of a node itself, it is not necessarily
stable across reboots and upgrades, and there is nothing else in the
respondd data that this ID could be matched against. Remove it.
This reverts commit 8d53ff54e5 ("respondd-module-airtime: add idx").
In case a radio exists, but is disabled, the survey request will return
successfully, but without data.
The code could not handle this case, as the newest_element_index would
be negative in this case, leading to json_object_array_get_idx returning
a null-pointer.
Check for a null pointer prior adding the PHY index, avoiding a
null-pointer dereference.

The noise value delivered by nl80211 is actually a signed int8. Thus it
must be interpreted as a signed value, too.
