Steven Rostedt ea4e2ad6f6 ktest.pl: Fix uninitialized var in config-bisect.pl
commit d3042cbe84 upstream.

The error path of copying the old config used the wrong variable in the
error message:

 $ mkdir /tmp/build
 $ ./tools/testing/ktest/config-bisect.pl -b /tmp/build config-good /tmp/config-bad
 $ chmod 0 /tmp/build
 $ ./tools/testing/ktest/config-bisect.pl -b /tmp/build config-good /tmp/config-bad good
 cp /tmp/build//.config config-good.tmp ... [0 seconds] FAILED!
 Use of uninitialized value $config in concatenation (.) or string at ./tools/testing/ktest/config-bisect.pl line 744.
 failed to copy  to config-good.tmp

When it should have shown:

 failed to copy /tmp/build//.config to config-good.tmp
