sched: Fix kthread_bind() by moving the body of kthread_bind() to sched.c

Eric Paris reported that commit
f685ceacab07d3f6c236f04803e2f2f0dbcc5afb causes boot time
PREEMPT_DEBUG complaints.

 [    4.590699] BUG: using smp_processor_id() in preemptible [00000000] code: rmmod/1314
 [    4.593043] caller is task_hot+0x86/0xd0

Since kthread_bind() messes with scheduler internals, move the
body to sched.c, and lock the runqueue.
