ktest: Fix result of rebooting the kernel

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.
