reserve_region_with_split: Fix GFP_KERNEL usage under spinlock
This one apparently doesn't generate any warnings, because the function is only used during system bootup, when the warnings are disabled. But it's still very wrong. The __reserve_region_with_split() function is called with the resource_lock held for writing, so it must only ever do GFP_ATOMIC allocations.
