ip6mr: Indentation not proper in ip6mr_cache_report()

Hi All,

Before sending the patch, I am writing this email to get your
attention please. As per my knowledge I can see ip6mr_cache_report()
has some indentation issues. Please have a look at the line 1085.

Sharing a patch based on the latest stable Linux.

Thanks,
