builtin/describe.c: print debug statements earlier

stefanbeller · gitster · commit cdaed0cf023a · 2017-11-16T11:12:51.000+09:00
When debugging, print the received argument at the start of the
function instead of in the middle. This ensures that the received
argument is printed in all code paths, and also allows a subsequent
refactoring to not need to move the "arg" parameter.
