[PATCH] attr: fix instructions on how to check attrs

["John Cai via GitGitGadget" <gitgitgadget@gmail.com>]

From: John Cai <johncai86@gmail.com>

The instructions in attr.h describing what functions to call to check
attributes is missing the index as the first argument to git_check_attr.

Fix this to make it consistent with the actual function signature.
