sh: Fix kernel thread stack corruption with preempt.
When I run a preemptive kernel-2.6.20 for SH7780, a created
kthread(pdflush) can not exit by do_exit() in kernel_thread_helper. I
think that the created kthread should have a room for 'struct pt_regs'
space on the stack top, because __switch_to() will refer to the space as
follows using 'regs = task_pt_regs(prev)' and next condition may be true.
