[PATCH] t7422: remove extraneous argument to printf

[Subhaditya Nath <sn03.general@gmail.com>]

The POSIX man page of printf(1) mentions -
> If the format operand contains no conversion specifications and
> argument operands are present, the results are unspecified.

In practice, this means some printf implementations throw an error
when provided with extra operands, thereby causing the test to fail
erroneously. This commit fixes that issue.
