[PATCH 2/3] ktest: Fix result of rebooting the kernel

From: Steven Rostedt <srostedt@redhat.com>

The command that is called that reboots the kernel may fail
but the return code is not passed back to the ktest.pl script.
This is because a ';' is used between the two commands and
if the second command fails, only the first command's return
code is returned. Using a '&&' between the two commands fixes
this.
