[PATCH] sched: Fix rq lock use through wrong spinlock api

[Frederic Weisbecker]

Now that rq lock is a raw spinlock, it needs to be manipulated
using appropriate helpers.

This fixes the following warning:

kernel/sched_fair.c: In function âtask_fork_fairâ:
kernel/sched_fair.c:1958: attention : passing argument 1 of âspinlock_checkâ from incompatible pointer type
kernel/sched_fair.c:1978: attention : passing argument 1 of âspin_unlock_irqrestoreâ from incompatible pointer type
