[PATCH] powerpc: Drop unneeded cast in task_pt_regs()

[Michael Ellerman]

There's no need to cast in task_pt_regs() as tsk->thread.regs should
already be a struct pt_regs. If someone's using task_pt_regs() on
something that's not a task but happens to have a thread.regs then
we'll deal with them later.
