mm/vmalloc.c: don't unconditonally use __GFP_HIGHMEM

Commit 19809c2da28a ("mm, vmalloc: use __GFP_HIGHMEM implicitly") added
use of __GFP_HIGHMEM for allocations.  vmalloc_32 may use
GFP_DMA/GFP_DMA32 which does not play nice with __GFP_HIGHMEM and will
trigger a BUG in gfp_zone.

Only add __GFP_HIGHMEM if we aren't using GFP_DMA/GFP_DMA32.
