s390/suspend: fix prefix register reset in swsusp_arch_resume

Browse source

The reset of the prefix to zero in swsusp_arch_resume uses a 4 byte stack
slot. With CONFIG_VMAP_STACK=y this is now in the vmalloc area, this works
only with DAT enabled. Move the DAT disable in swsusp_arch_resume after
the prefix reset.
