logwrapper: don't confuse the static analyzer.

The static analyzer didn't like this code:

> system/logging/logwrapper/logwrap.cpp:165:9: warning: 1st function
> call argument is an uninitialized value [clang-analyzer-core.CallAndMessage]

> system/logging/logwrapper/logwrap.cpp:514:9: warning: 1st function
> call argument is an uninitialized value [clang-analyzer-core.CallAndMessage]

And it seems fine to just rewrite in a more "obviously correct" fashion.
