[PATCH bpf-next 1/2] x86: disable HAVE_ARCH_HUGE_VMALLOC on 32-bit x86

[Song Liu <song@kernel.org>]

kernel test robot reported kernel BUG like:

[ 44.587744][ T1] kernel BUG at arch/x86/mm/physaddr.c:76!
[ 44.590151][ T1] __vmalloc_area_node (mm/vmalloc.c:622 mm/vmalloc.c:2995)
[ 44.590151][ T1] __vmalloc_node_range (mm/vmalloc.c:3108)
[ 44.590151][ T1] __vmalloc_node (mm/vmalloc.c:3157)

which is triggered with HAVE_ARCH_HUGE_VMALLOC on 32-bit x86. Since BPF
only uses HAVE_ARCH_HUGE_VMALLOC for x86_64, turn it off for 32-bit x86.
