Masami Hiramatsu 615d0ebbc7 kprobes: Disable booster when CONFIG_PREEMPT=y ...

Disable kprobe booster when CONFIG_PREEMPT=y at this time,
because it can't ensure that all kernel threads preempted on
kprobe's boosted slot run out from the slot even using
freeze_processes().

The booster on preemptive kernel will be resumed if
synchronize_tasks() or something like that is introduced.
