Subject: [PATCH] testsuite: repair read of uninitialized memory
References: https://github.com/kmod-project/kmod/pull/15
References: https://github.com/kmod-project/kmod/issues/14

Function ``test_backoff_time`` does not initialize ``delta``, and
``get_backoff_delta_msec`` then performs a read from uninitialized
memory with the ``!*delta`` expression.
