If CONFIG_DM_DEBUG_SPACE_MAPS is enabled and memory is fragmented and a sufficiently-large metadata device is used in a thin pool then the space map checker will fail to allocate the memory it requires. Switch from kmalloc to vmalloc to allow larger virtually contiguous allocations for the space map checker's internal count arrays.
