logging: fix printing of '\0' when filename printed last
As was demonstrated in I54bf5e5c036efb1908232fe3d8e8e2989715fbb3, when the logging is configured to print the filename *after* the logging message, each logging line contains an artifact - '\0'. The problem is that the 'len' variable is not updated. Fix this. Change-Id: I5c920a0d5c1cf45bcdd327b39e33d63346b4f51c Fixes: I393907b3c9e0cc1145e102328adad0a83ee13a9f
