sched: Fix cond_resched_lock() in !CONFIG_PREEMPT
The might_sleep() test inside cond_resched_lock() assumes the
spinlock is held and then preemption is disabled. This is true
with CONFIG_PREEMPT but the preempt_count() doesn't change
otherwise.
Check by starting from the appropriate preempt offset depending
on the config.
