[committed] Fix uninitialized var in dwz_one_file

[Tom de Vries]

Hi,

The commit dbfecee "Move hardlink handling out of dwz function" added
initialization of res->res in dwz_files_1, but failed to do the same
in dwz_one_file.

Add the missing initialization by factoring out the initialization code from
dwz_files_1, and using it in dwz_one_file.

Committed to trunk.

Thanks,
- Tom

Fix uninitialized var in dwz_one_file

2021-03-25  Tom de Vries  <tdevries@suse.de>

	* dwz.c (init_file_result): Factor out of ...
	(dwz_files_1): ... here.
	(dwz_one_file): Use init_file_result.
