[PATCH] diff-lib.c: Fix diff-files --diff-filter --quiet exit code

Given the following status:

	$ git status -s
	 M bar
	UU foo

There is an unexpected difference in the return code of git diff-files
when used with --quiet as opposed to --exit-code:

	$ git diff-files --diff-filter=U --quiet
	$ echo $?
	0

	$ git diff-files --diff-filter=U --exit-code
	<usual output, lots of 0's and U<TAB>foo>
	$ echo $?
	1

Notice the different return codes. Now, according to the documentation,
--quiet implies --return-code. However, the return code of the former is
clearly not correct if --return-code was supposed to be on.

This patch removes a useless bit of code that caused the return codes to
differ.
