mm: disable preemption in apply_to_pte_range
Impact: bugfix
Lazy mmu mode needs preemption disabled, so if we're apply to
init_mm (which doesn't require any pte locks), then explicitly
disable preemption. (Do it unconditionally after checking we've
successfully done the allocation to simplify the error handling.)
