logging: make nm_logging_enabled() inline function

Basically every logging statement is wrapped by a nm_logging_enabled()
to evaluate the function call of the logging lazy.

Make the function a candidate for inlining, it safes some space. On
a default build it goes for me from 2580584 to 2560104 bytes (20k).

   $ ./autogen.sh && make && strip ./src/NetworkManager
