Revert "Base air absorption on the distance attenuation"
...
This reverts commit c7c2f9385f7bfde9962eb7743770679cca07181e.
Fundamentally wrong. The -6dB rolloff is every doubling of the distance, and
the (scaled) -0.05dB rolloff is supposed to be every additional unit.

Although the properties are set as context attributes, they are queried from
the device. If multiple contexts per device are ever supported, it would not
be straight forward about where to read the values from. This way, the
attributes can be treated as device-specific attributes that are updated when
a new context is created.
