x86/jump_label: expect default_nop if static_key gets enabled on boot-up
net_get_random_once(intrduced in the next patch) uses static_keys in
a way that they get enabled on boot-up instead of replaced with an
ideal_nop. So check for default_nop on initial enabling.
Other architectures don't check for this.
