[PATCHv4 5/7] builtin/describe.c: print debug statements earlier

[Stefan Beller <sbeller@google.com>]

For debuggers aid we'd want to print debug statements early, so
introduce a new line in the debug output that describes the whole
function, and then change the next debug output to describe why we
need to search. Conveniently drop the arg from the second line;
which will be useful in a follow up commit, that refactors the
describe function.

This re-arrangement of debug printing is solely done for a better
refactoring in the next commit, not to aid debugging git-describe,
which is expected to have the same information readily available
with the new prints.
