powerpc: Move stack randomization after syscall_enter_from_user_mode()
add_random_kstack_offset() is invoked before syscall_enter_from_user_mode()
establishes state. That's wrong because add_random_kstack_offset() calls
into instrumentable code.
Move it after syscall_enter_from_user_mode() to ensure that state is
correctly established.
