Randomizing the syscall stack can only happen after state is established

it happens the better.

Provide two new macros to consolidate that:

   - enter_from_user_mode_randomize_stack()
	enter_from_user_mode();
	add_random_kstack_offset_irqsoff();

   - syscall_enter_from_user_mode_randomize_stack()
	enter_from_user_mode_randomize_stack();
	syscall_enter_from_user_mode_work();
     
to reduce boiler plate code.

Those are macros and not inline functions as the latter would limit the
stack randomization scope to the inline function itself.
