'git add' could call crlf_to_git() twice, and this caused that the same
crlf warning being display twice. The first time crlf_to_git() is called
when a file is added to index, and it could be called the second time
during writing the index.
This patches sets safe_crlf to false before the second call.

I think I have found the cause. It can be seen from the following trace:

This patch works for me but it certainly needs better testing.
