ifb: Include <linux/sched.h>

commit b51c3427e95b ('ifb: fix rcu_sched self-detected stalls', commit
440d57bc5ff5 upstream) added a call to cond_resched(), which is
declared in '#include <linux/sched.h>'.  In Linux 3.2.y that header is
included indirectly in some but not all configurations, so add a
direct #include.
