Small oversight in hard_link_one

[Rolf Grossmann]

Hi,

while looking over my flags patch for the upcoming 3.0 version (more on
that later), I noticed a small bug was introduced into hard_link_one
when changing the return codes. As a result, in the rare case of the
hard link failing and the verbose option not in use, rsync wouldn't
try to copy the file, either. Here's the fix:

 			code = FINFO;
 		} else

Bye, Rolf
