x86/entry: Get rid of pt_regs_to_thread_info()

It was a nice optimization while it lasted, but thread_info is moving
and this optimization will no longer work.

Quoting Linus:

    Oh Gods, Andy. That pt_regs_to_thread_info() thing made me want
    to do unspeakable acts on a poor innocent wax figure that looked
    _exactly_ like you.
