If a callback returns a negative value to `git_config*()` family,
they call `die()` while printing the line number and the file name.
Currently the printed line number is off by one, thus printing the
wrong line number.
Make `linenr` point to the line we just parsed during the call
to callback to get accurate line number in error messages.
